I hear you and, as I said, I'm sure the data was somewhat watered down by the Case Keenums of the world and other names, which I'm sure played a role there. I think we saw a couple of guys whose names I can't even remember go down like that last year in one game if I recall ... although which one it was escapes me.
But again, percentage-wise - at least when it comes to the elite or notable starters among the top teams - the guys I mentioned were all players who were injured down the stretch last year. With Purdy being the one exception.
I don't know any mobile/dual threat QBs I can think of who will play into their 40s. I feel pretty confident anyone who pulls that off will be the exception, not the rule. And that's even with the way the officials tend to protect those guys. It's like anything else, the more you run, the more prone you are to taking a shot that can sideline you.
Again, not saying you're wrong, especially not knowing how they broke it down. A lot of guys get hurt all season and many of them are guys we don't remember. Collectively, that study is probably pretty even. But among the starters or marquee guys, I would say it's probably a little different and those are the ones I was thinking of. And I think the career longevity thing is probably accurate. Or at least, it has been so far based on who we've seen make it into their late 30s or beyond.
