Keep in mind his assistants were idiots and he's had bad injuries each season here. He has to change in that regard, he has to make sure the risk is lowered for all of these injuries.
There is a risk to changing coaches and going to a guy that you really don't know what you are going to get from. I don't think Cameron is that good, and the only one on the market that I really like is Ron Rivera. And who knows where he may go.
Whether you like it or not, it's time to live with this move.
