I think that it has taken a deft touch at coaching for the Seahawks to get the most out of Marshawn Lynch all these years. He is very stubborn and eccentric. He nearly didn't play last year and went on his own strike. What did the team do? Pete Carrol killed him with kindness through the media. "He's a wonderful kid. I just hope he comes back some day." Lynch then came back for a guaranteed contract and the same amount of money that he would receive even if he didn't go on strike.
In return, Lynch makes the rest of the Seahawks offense work and makes the coaches look like geniuses. I think that the Hawk philosophy may be more effective than other systems for key players. Like the Rangers getting good results from Josh Hamilton by getting him his own life coach and always being nice to him. I think that other players are going to do what they are going to do no matter what the organizational philosophy is. I don't think you can coach Felix into having better games.
Two cents.
