Boomer I agree with you. The diff is you can name the o-linemanIe fowler Faine verba Brown, but they were not in same year and for one reason or another have not done chit. Verba has yet to play a full season for them Brown has been gone 3+ years, Fain was hurt last year. Thay also lost 4 lineman this offseason. Truth be told Green has played 7 good games his rookie year before and since nothing. Suggs is very good but came on late last year. Receivers are good but had some growing pains, they do have a tendency to drop balls.
Now the opposite side against Couch and this is teh biggest. The hype over couch was inflated, Boomer is dead on he was a product of Mumme's system, he never played in a pro style system, almost exclusively out of teh shotgun if i am remembering it right. He was also thrown to the wolves from teh start when he needed to sit and learn. His arm strength is not great, better than Jays but not a ton. He never got away from looking at his receivers, he does alright for awhile then reverts back to his bad habit. He presses to much and forces passes he has no business forcing at times as well. He has one big similarity as Jay, he is not consistent at all.
Basically Couch did not have great supporting casts togethor at the same time, he did not show that he had any more potential than what he has shown to date. To me he is not a safer risk than Feeley. He has his questions as well. AJ has questions yes, but at least his questions are questions of the unknown with upside potential, rather than questions of which is the true qb, the one that had the potential and failed to realize it or teh one with a bad supporting cast. To me the one who has already had his chance and made nothing of it is the bigger risk, because you are betting he wont play as he already has, whereas with AJ, you want him to continue the play and build on what he has shown.
