I have a feeling he is going to be a pain for only a couple years. He is making these guys believe they can re-negotiate at will and GM's will get or are tired of it. McKenzie lost money sitting out and if Walker and Jackson do so will they. NFL life is short so they better play while they can. Especially Jackson who if he sits out a year will be in non-playing shape when he comes back and may never get back to his current level of play. Once these guys figure out they are losing money by listening to bad advise they will dump him.
