The problem with Fish is that he's a defensive head coach and the defense has been pedestrian since he arrived. Nowadays in the NFL you pretty much need to lock up an offensive or defensive genius as the head coach since they get hired away so effin quickly. Due to that, it is possible to be an overall motivator type IF you have a great eye for your coordinators. But Fish clearly does not. And that's gonna be his reason for failure unless he rectifies it.
Starting with Williams, for all the flak we give him, I still think he is a quality coordinator. He's gonna need some time to shape this unit, clearly. They are improving incrementally, like the run defense for example, and that is in the face of injuries. The key is the question of whether the right piece is in place there? I think yes, that Williams is a winner and his track record gets him a second year to shape his unit.
But not Schotty. This whole group has been under his leadership for 3 years now, and they execute poorly, and are terribly predictable. After the interception today you just knew they'd turtle, and KC knew it too. Execution is part of his responsibility as well. Bill Walsh used to have the 9ers re-run the same play until it was perfect every time in practice. I don't know how the Rams schedule their offensive learning compared to other teams, but the results are not there.
If I'm the owner I would tell him I can't take any more Schotty. I want an innovative offensive mind brought in and that does not mean a pass happy guy either just someone who knows offensive balance and gets results. If he would not accept that, I'd terminate his contract and move on with the coaching search.
