if that's really the case, then Arians should point the finger at one person and one person only...himself. it's his jobs staff to teach the offense to it's players and if they ain't getting it, that's on him.
personally, I think it's all smoke...or hubris on Arians' part. He didn't draft a QB, didn't go after Alex Smith and hitched his wagon to a guy we got for a 7th round pick. Either he's not man enough to admit that decision might have been a mistake...can't admit it was a mistake at this point of the season...or we've got a real problem at HC. Time will tell, but continuing to bash anyone but Palmer is getting real old.
Still can't believe he laid the flea-flicker pick on Floyd also. Palmer throws that ball far enough and Floyd doesn't have to stop and come back to the ball to be a defender.
