I'm kind of sick of all the blog writers and fans decrying the terrible QBs. McKee was worth a 1st round pick last year (hahaha) and now all of the sudden he's trash. No inbetween. I expect it from the fans, but these guys like Kempski, BLG, etc. - they are just fans pretending to be journalists. No clue at all.
The friggin' preseason games mean NOTHING compared to the practices, nothing. People just don't get it. And Andy Dalton is a 3-time Pro Bowler, 15+ years in the league - like that means nothing in a room where the offense is really different for the first time in a long time and you have a delicate situation on the offense with the revolving door OCs and a Super Bowl MVP QB learning to play differently.
If guys can make a contribution (see Payton lining up on STs) they make the roster - pretty much period. If they can't they are either on IR (if it's physical growth they require) or the back half of the practice squad. This isn't hard to figure out, the front office shows the fans every year, but nobody picks it up.
These guys are managing personnel, coaching, etc. for their JOBs. Pretty much everyone (except Howie, probably) knows they could be gone in a year if things break really bad every year. They have to win - this is not a franchise in a rebuilding mode and they are not playing dynasty fantasy football.
I really don't have a clue how Tanner McKee would do if Hurts went down. I think he's probably better than many backups, but the people seeing him every day likely have a far better idea of what he's capable of. I probably do have a little more of a clue about Dalton - he probably can competently run the offense, but is not going to light it up or open up the run game. Payton is probably 2 years at least away from making a judgement on that and in the meantime can add value on STs which allows them to keep another player on the roster that they may not have been able to because they were unsure about putting them on the field on STs - you don't get that value from many QBs.
