Let's not forget last year's offensive performances. Would Kyle have left Griffin in to get his knee blown up? No. Would Kyle force a DC to run the wrong defense for the personnel? No.
Take personnel away from the HC, help him hire an OC, and I think he would do pretty well. He'd learn and adjust.
But what the hell do I know.

If Rex Ryan gets canned it could be fanboi Snyder's wet dream to hire Kubiak as OC and Ryan as DC with Shanahan staying as HC. That's the type of move he longs for. Although I do like Ryan as DC. He seems to have a good eye for defensive personnel.
