We did roll the dice on Bryant, and we crapped out. How long do you keep trying on a guy? Five years? Eight years? At some point, you have to say enough is enough, and that's what Parcells did.
And it's more than a "nuisance" when a guy freelances routes, throws constant temper tantrums, and maybe even won't come out of a game when he's asked to.
And BTW, I don't think it's such a slam dunk on getting the hands right when catching. I'm right handed, and if a pass is coming to my left, I instinctively put my right hand above my left (unless the pass is very low) because I don't feel as comfortable with the left hand "blocking" the ball (for lack of a better term) when the left hand is on top. Sure, Morgan is a professional and he should have had this addressed at some point, but sometimes coaches, especially poorer ones, don't fix every small flaw in talented players.
