Coaching staff get's to see Beck every day in practice. They know much more about the game of football than you do. It's pretty obvious when someone just doesn't have it, and Beck doesn't have it.
The thing you don't seem to understand is Beck is a 28 year old, 2nd year player. If he was say a 22 year old 2nd year player, then maybe the coaching staff keeps him? But at 28, it's a total waste of time to try and develop him. If he was a 28 year old vet who's played a few years, perhaps the coaching staff keeps him?
What part of Parcells and NOT the coaching staff made that decision don't you understand?
And I would rather have 10 years from a quality QB than 15 years from a crappy one. So, until Miami had a QB of the future that had been proven to be better than Beck (Henne hasn't proved squat yet) I'd just as soon try to develop that second round pick instead of waste it.
Parcells not Sparano, decided to waste it.
And yes I will hold him accountable if Beck succeeds elsewhere.
And after his 108 passer rating showing poise, zip AND accuracy which none of our current QBs have, Beck is already on his way to doing just that.
