Belcheat proved he was the best at cheating the system. They were succesful because of that, an owner with zero scruples, and Tom Brady.
The problem is, Beane isn't sharing the blame by being promoted. I think we will find out fast, if McD had too much power over player personnel.
The first task, nail the coaching staff. Then what we do at WR will be a big tell. If we don't pull a trade at FA for a #1 talent. Or take a swing in the draft for one. Then we see drafting strategy was truly Beane's all along. The offseason got interesting, that's for sure. Hard decisions need to be made with the roster. And how the players perceive this change will be huge.
