They used to have 14 reg. season games, and 12 before that. It's been 16 since 1978 (I had to look that up to remember the exact year). The game has changed since then- it's not quite as brutal. I asked John Hannah once 'how did the rules change throughout your career'? He thought about it and said 'When I started, if a safety was blitzing on me, I'd stretch out my arm, and the safety would run full speed into it, and sometimes neck first! And that would thus stop the safety blitz! But then they had to change the rule because of me (Hannah). No more clotheslining'.
I think adding a couple of games wouldn't be any big deal. There's always going to be injuries. Some guys are just meant to be injured. The guys that go above and beyond every game. A Gronk. A Fred Lynn in the outfield. Change happens-like they finally lengthened the xtra point. The American League added the designated hitter in 1973. People said 'now there's gonna be more more batters getting thrown at, because the pitcher doesn't have to bat and take his medicine'. Didn't happen.
Really, you think two more NFL games is going to make that much difference in injuries? Okay, then increase the gameday roster from 45 to say 55. But they'll have to increase player pay by 2/16, plus pay more players, plus start the games earlier (August) or end in the third week of February. As far as having 2 games where the starters don't play, they already have that! It's called preseason!
And don't use Gronk as an example of unnecessary injuries and punishment. As we all know, yeah he's bigger and stronger that most of the players, but he got hit So much harder than 95% of the players, god love him. And he hit the other players extra hard too. Andrew Luck? Always put himself in harm's way. Brady, on the other hand, doesn't get hurt as much, because of his intellegence, and the quick toss system, which is also intelligent. Guys like Luck, a Ben R, an A Rodgers, they're talented, but dumb.
2 more games? No big deal. Unless you have to pay for all 18 regular season games as a fan. 18+ including (expanded?) playoffs. And I don't think they'll make the preseason free.
