Why do we always expect that the new QB coach / OC can fix a QB? That somehow his style of coaching or new type of offense will make an iota of a difference?
It hasn't happened here in 15 years. We've probably had more than a dozen QB's and even more QB coaches and OC's. Promises of the QB will fit the style, we will use the QBs strengths, we will improve the line / run game and they will turn into winners, the QB can run, the QB will stay in the pocket, the QB just needs to throw it away and go on to the next play, "we will dictate to the defense" is always a good one, on and on and on....
The truth in fact is that the QB usually regresses. But every off-season we drink new Kool-Aid.
