It is a little frustrating to know how good some of the past Pats were and to see that they are unknown or, worse, ignored by younger fans. There seems to be a perception that because pre-2001 teams didn't win any Super Bowls then somehow they weren't relevent. I'm not mad that younger people mostly don't care, but more I wish they knew how good those guys really were.
If you ask me how many of the '76-78 or '85 era Pats would make the current team in a fair tryout (assuming they were the same now) then the correct answer is "a shitload". Modern players tend to be more athletic and certainly bigger on average than they were in those eras, but on sheer talent there is no question that we were loaded at times in the past.
Imagine Brady throwing to Stanley Morgan. Imagine a backfield comprised of Haynes, Ray Clayborn, Tim Fox and Fred Marion. Every DB on the current roster would be replaced. I believe that many of the great linebackers we've had like Tippett, Nelson, Sam Hunt and Don Blackmon would easily make the roster. Mayo would be the only survivor.
Could Bill Belichick find a role for Sam Cunningham even though he was a fullback? I imagine he could surely come up with something. The guy was a freak of nature.
I'm not sure Russ Francis could beat out Gronkowski as a starter, but it would be an damned interesting competition.
Mac Herron vs. Woodhead? Child, please.
I'll quit there, but probably only a dozen guys from the current squad would make the 53-- if that.
