Pioli not addressing the back up option better than he did in the off season was a major failure on his part. He gift wrapped Cassel as his starter since Manning rejected a visit to him. Cassel was his boy all the way, he wanted to look like a saint with Cassel and RC went along for the ride with him.
RC was all over wanting RG3, Manning, anybody but Cassel and yet Pioli drove the bus right off the cliff and brought in Brady Quinn. Now if Quinn lights it up, he can take credit for that too.
Stanzi has not had a chance to play, BTA he hasn't shown enough to beat out anybody. Tanney is on IR, but a long shot to even make camp next year with Cassel & or Quinn gone. Not addressing the QB issue is his failure.
