Honestly? it was just a matter of time. they hit too hard these days, running QBs always, always wind up hurt. The only one who can take the hits is Cam , he's a monster.
you see that personal foul on the Ravens for Helmet to Helmet? It was bullshit...like it was intentional...
Dude got hit in the chest, and his helmet happened to hit, due to the angle.
I think it's relative, with certain players and positions, they can hit hard, but with others you have to watch it.
I do agree though, a QB that runs well, gets hurt more. It's the nature of the beast. But, due to the defense being so damn quick now, the pocket collapses quicker, so now more qbs are gonna have to have a good options game, great speed and agility. No more just sitting back.
