I believe the answer to your quandry is simple. Last year and for 2 years before that Wanny built his ENTIRE franchise around ONE player. At that time both Chambers and McMichael had yet to emerge as true athletes or play makers on the pro level. Think about how STUPID that is to do. I mean c'mon the guy did not have a creative cell in his body. And he was so absolutely out of his depths that he did not even know how to hire offensive personel to help bring in and utilize talent. Instead he used a stylized, boring, ineffective offense and even then Ricky tore it up.
Even if Ricky had the psychology or mental set of players like say Jerry Rice in his prime or even Emmett Smith in his, this move is absolutely STUPID because of injury. It was a setup for disaster and disaster is what we got - thanks Dave!
Nicktator on the other hand will have a team that can and will win without any one or any multitude of players. Ricky flakes out, we got Ronnie, Ronnie goes down, we got Kay-Jay, Kay Jay goes down we got Lamar and so on. The Nicktator has everyone pushing themselves such that no-name players will emerge to create a synergistic process in which any piece is adjustable. Obviously some easier than others, but this is where Belicheck has had SO much success. He probably would not have necessarily been a great coach in the 70's or 80's or even the early 90's, but the guy is a genious for today's salary cap systems.
The days of being a dominant dynasty are over, The Steelers, The 49ers and so on because teams must be solid accross the board. Belicheck uses a system where versatility is valued and playing to his athletes strengths is emphasized. Then winning starts to happen and becomes contagious. He does not have the best offensive line but the system allows for players to have massive success because he plays to there strengths.
This is where the Nicktator will prove his genious as well. So as Arnold once said "Relax, you'll live longer"!
