i think we need to be physical with your WR's at the line to disrupt the timing

We can't let brady have all day in the pocket. Play physical at the line, blitz and don't worry about being deep down the field. I think teams get too concerned about the big play against the patriots. We need to take it to the New England Patriots and make THEM play left handed.

I have a feeling they are going to make Kap beat you's.

The real key to the game?

please tell Welker there will be L andmines in the middle of the field on sunday.

You don't understand the situation at hand. Offensively the Patriots have an answer for anything the 49er defense can draw up. This isn't the Saints or Packers. You say make the Patriots play left handed. Too bad they're ambidextrous. I hope the Niners do blitz. I'll be looking forward more long TD passes to Lloyd and Stallworth.

 

[94niners]

No one here is counting it as a win but we are confident in our team. We've seen this team grow from losing 3 games early in the season by 4 pts that could have been won into a team that is peaking when it matters most. This should be a good game. Good luck.

That is true. The Patriots are definitely in Ultimate Destiny mode, while the 49ers are still trying to figure things out on offense.

Most Pats fans don't consider any game in the bag.
IMO, this is a Super Bowl preview.

Maybe, but if I weren't a homer my money would still be on the Giants representing the NFC in the Big Dance.

Even if it is a SB preview, if the Pats lose that will have no bearing on the outcome of the SB. BB (Bill Belichick) is deadly the 2nd time around.

Except when it comes to the Giants. And sadly for Pats fans, I think they are clearly the best team in the NFC right now.

Very interesting analysis. The numbers back up the obvious, that the 49ers are clearly superior on defense and the Patriots are clearly superior on offense. I think what gives the Pats the advantage, though, is their third down and redzone offense. If the 49ers trade field goals for touchdowns in this, the game will probably end up looking like the 2007 AFC Championship.

 

[Oswlek]

The Patriots looked pretty unstoppable yesterday, no doubt.

But then, so did the Packers against this Texans team. They beat them IN TEXAS 42-24. And we beat the Packers in Green Bay 30-22, despite the refs giving them a touchdown on a bad call.

So, while the Patriots look like the best team in the league, I wouldn't count this one in the bag just yet.

Good, reasonable post. I hope you stick around all week.

 

[midgar8784]

Seems like some Pats fans like to bring up the 9ers loss against the Rams in a few forums but forgot that the Pats lost at home on opening day against the Cardinals.

Yeah but it was not a couple weeks ago....

In the bag? Maybe you misunderstood, we did not come over to the niners board and claim victory like your counterpart did...so maybe you need to tell your own fans to not count anything in the bag.

This stat:

No QB since at least 2008 has a higher Total QBR than Colin Kaepernick through first four career starts. (Sando)

is about to change...

This is based on common opponents (how many, small sample?, early games or more recent games wh/ I would weigh more heavily) and I don't have time right now to determine the teams involved unfortunately. Based on point diff of those common opponents and adding in home field this looks like a tie game.

One caveat, the Pats have improved tremendously in recent weeks b/c of health and b/c the young players have (finally) learned the system. This Pats team is far better than, say, the week 3 team. Incremental improvement is a BB staple. I can't say that the 49ers are far better now than early in the season, esp with fundamental changes at QB and subsequently, the offensive system. Idk, may be better but may not be.

 

[Beaglebay]

4 starts? Really? What a monster stat.

 

[anderson]

I think there's no doubt that this is the best defense we've faced all year, but I think we have a unique ability, to the NFL, to create mismatch problems for any defense we face.

I also think we're going to be decent at stopping the 9er offense, because there isn't all that much to it. I don't mean any offense by that, but I don't see the 9er offense as very tricky. Again, we'll try to stop the run cold and have Kapernick try to beat us in the air.

When all is said and done, it has to come down to the two Smiths. If we keep them away from Tom, then I think we walk away with this one.

Sadly?
You'll find many Pats fans hoping above hope for a rematch with the Giants just to set the universe right again. This iteration of the Giants doesn't give me a moment's pause. It was their fearsome pass rush + lucky Eli that did us in for both games. Those pass rushers are gone or older and karma seems to have left Eli this year. Not to mention our OL now is far superior to those OLs. If we do get a rematch with the Giants this SB, I'll be jumping joyously. No way this Pats team loses to this Giants team.

I think we can safely discount doublecheck that comparison as being statistically invalid for its small sample size and b/c 3 games were early in teh season.


This is much more relevant & doesn't even include last night's dominating performance.

Regular season totals, through Week 13

Revised as of 12/4/2012

These are the Football Outsiders team efficiency ratings for 2012, measured by our proprietary Defense-adjusted Value Over Average (DVOA) system that breaks down every single NFL play and compares a team's performance to a league baseline based on situation in order to determine value over average. (Explained further here.)
OFFENSE and DEFENSE DVOA are adjusted based on strength of opponent as well as to consider all fumbles, kept or lost, as equal value. SPECIAL TEAMS DVOA is adjusted for type of stadium (warm, cold, dome, Denver) and week of season. WEIGHTED DVOA represents an attempt to figure out how a team is playing right now, as opposed to over the season as a whole, by making recent games more important than earlier games.
As always, positive numbers represent more points so DEFENSE is better when it is NEGATIVE.

I will say that Welker's going to need to show the **** up next week on offense (he was fine on PR). I catch a lot of shit for harping on Welker's hands, but was that 3 "rare drops" for Welker last night?

You want a contract Wes? Show up, and enough of this already.

49ers’ offense could use some hurry-up

Posted on December 10, 2012 at 8:37 pm by San Francisco Chronicle in http://blog.sfgate.com/49ers/category/49ers/

49ers’ offense could use some hurry-up
Quarterback Colin Kaepernick is a fast runner and throws a football even faster, but one part of his game could use a bit of quickening, Jim Harbaugh acknowledged Monday.


The 49ers were forced to use four timeouts in Sunday’s 27-13 win over the Dolphins to avoid delay-of-game penalties, including two in the first 14 minutes of the third quarter.
The play calls were being delivered on time and the personnel substitutions weren’t tardy, according to Harbaugh. He said Kaepernick bears some of the responsibility for the wasted timeouts.

“Well, it’s his responsibility,” Harbaugh said. “It’s everybody’s responsibility, yeah. The tempo of how you operate needs to be better. … We need to be better at that. And that’s happened before and we just have to, just like your Pop Warner coach would tell you: Call the play, break the huddle, get up to the line of scrimmage, get set.”
Overall, however, Harbaugh was pleased with the performance of the second-year quarterback, who completed 18 of 23 passes, posted a 100.2 rating and matched the franchise record he set the previous Sunday with a 50-yard run, his latest for a score.
“I think for a guy who’s only started four games now, I think he’s doing it at a pretty darn high level,” Harbaugh said.
Game to prime time: America will get a heavy holiday dose of the 49ers.
The NFL announced San Francisco’s afternoon visit to Seattle on Dec. 23 has been flexed to prime time, meaning the 49ers will play on NBC’s “Sunday Night Football” for the next two weeks. San Francisco will travel to New England on Sunday.
San Francisco’s game against Seattle will replace the originally scheduled and now-unappetizing meeting between the Chargers (5-8) and Jets (6-7).
Moss’ near-TD: In the third quarter Sunday, wide receiver Randy Moss nearly hauled in a 47-yard, flea-flicker touchdown from Kaepernick. The catch was exceedingly difficult with Dolphins cornerback R.J. Stanford clinging to Moss’ right arm.
On Monday, Harbaugh took care not to criticize the no-call on the play.
“He had some adversity trying to make that catch,” Harbaugh said, drawing laughs. “There was some adversity involved there.”
During the game, CBS analyst Dan Dierdorf didn’t bother to pull any punches.
“I mean, seriously, how do they not throw a flag on Stanford?” Dierdorf said. “He was grabbing Moss’ arm for about 20 yards.”
Eric Branch is a San Francisco Chronicle staff writer.






Poor clock management vs NE? 49ers will be DOA.

The Chahgahs and jetsam flexed out of prime time. Merry Christmas from the NFL :jclap:

SAN FRANCISCO -- Colin Kaepernick's "hot hand" has cooled, but that's not the point, anymore.
Lukewarm Hand Kap is Jim Harbaugh's man, he's the 49ers' quarterback, and it's on him to grind through tough games and win.
Which is what Kaepernick managed to do Sunday in his fourth NFL start, and yes, "manage" is exactly the right word.
On Sunday, Kaepernick managed the game, kept the 49ers offense out of trouble and had some frustrating moments, too.
Then -- voilà! -- Kaepernick broke off a stunning 50-yard read-option touchdown run to seal the 49ers' 27-13 victory over Miami at Candlestick Park.
"He made a good read -- everybody came to me and Mr. Everything did his thing," running back Frank Gore said.
Basically, Kaepernick was Alex Smith-plus: A steady QB who also can run or throw for a TD at any random moment.
All of that explains why Kaepernick is playing and Smith isn't, even though Smith can do many of these things and has done them often.
Kaepernick is playing because of the "plus" part, even if that's only one bonus play a game.
"Thought he managed the game well," Harbaugh said of Kaepernick, who completed 18 of his 23 attempts for 185 yards. "Thought he did a good job, generally."
Hmm, does that sound like a description of another 49ers QB you know?
On Sunday, it wasn't all offensive fireworks for Kaepernick; quite frankly, it wasn't all very good.
"I wish I had a few
<hr class="articleAdRule">

<hr class="articleAdRule">
throws back, a few different decisions," Kaepernick said.He lost the ball on a sack on the fourth play of the game -- luckily for him, 49ers right tackle Anthony Davis recovered -- and the Dolphins defense seemed to confuse the second-year QB at times.
The 49ers burned several timeouts when the play clock was running down just as Kaepernick got the offense to the line; they were out of timeouts for the final 14 minutes of the game.
Meanwhile, Kaepernick was sacked four times, and the 49ers didn't score a touchdown until Miami set them up by losing a muffed punt.
"We got beat a couple times, just got beat up front," Harbaugh said when asked about the sacks. "And one time for sure he got fooled by the coverage."
Of course, Kaepernick came within a blink (or an uncalled pass interference) of a deep flea-flicker bomb to Randy Moss in the third quarter.
But NFL games are mainly won and lost on third down, and the 49ers converted only one out of their first nine third-down tries in this game.
Then, on their 10th third down of the game, it was third-and-5 at midfield with just over two minutes left and the 49ers hoping to kill the clock.
Kaepernick, who hadn't run much all game, faked to Gore going right and galloped around the left side, past a few defenders, and just glided into the end zone.
In celebration, Kaepernick kissed the tattoo on his right arm and -- this is so Kaepernick -- hours later tweeted a picture of the moment with a comment:
"Score a touchdown, kiss your tattoo. Kaepernicking."
And there you go: man of few words with the media, but fascinating everywhere else.
That's the 49ers' offensive catalyst now -- it's not a bad thing, it's just different.
No, the 49ers offense is not exactly peaking for the playoffs or revving at full-throttle as they head into the next two huge road games at New England on Sunday night and then at Seattle.
They're probably not beating Tom Brady's Patriots going 2 for 10 on third down, let's put it that way.
Instead, they're in a December adjustment period, with a young QB, working in new formations to take advantage of his skills, and hoping to rack up victories along the way.
But the 49ers knowingly put themselves in this spot by switching QBs at such a late stage of such an important season, and now it's on Kaepernick.
He has to be Alex Smith ... and more.
"We can just do more with Kap because he can run with the ball, very athletic," Gore said. "But basically it's the same (offense), just a little bit more read-option."
The 49ers want Kaepernick to manage the game, which he did Sunday.
And they want him to be spectacular when the spectacular moment arrives, and again, he did that, too.
It wasn't close to perfect. But, after last week's loss, it's what the 49ers needed.
They will need more Kaepernicking in the coming weeks, for good or bad, and they know it. Ready or not, here it comes.

Here's another statistical comparison that seems relevant

The Relativity Index

Through Week 14 of the 2012 Regular Season

About the Relativity Index. The Relativity Index measures the performance of each team relative to the performance of its opponents in all other games. Essentially, it adjusts for the quality of competition each team faces, and spits out a number that tells us how greatly a team overachieved, or how badly a team underachieved, relative to the quality of competition. You should pay attention to the Relativity Index because it's the indicator we use to adjust for the quality of each team's competition.

For example, if Team A scores 25.0 PPG, and its opponents surrender 20 PPG in all of their other contests, Team A is +5.0 PPG on offense. If Team A surrenders 20 PPG, and its opponents score 25 PPG in all of their other contests, Team A is +5.0 on defense. This equates to a total Relativity Index score of +10.0 PPG. In other words, Team A is 10 points better than the average performance of its opponents.

PS = points scored, on average, by that team; OPA = opponents' points allowed, on average, in all other games; PS-OPA = the difference in those two numbers; PA = points allowed, on average, by that team; OPS = opponents' points scored, on average, in all other games; OPS-PA = the difference in those two numbers; REL = Relativity, the sum of PS-OPA + OPS-PA, giving us the margin by which a team outscores, or is outscored by, its opponents compared to their performances in all other games.
