While I hope McGahee turns out to be the best RB in the league, he has certainly not shown us that. Therefore I find it impossible to believe that he is posturing for renegotiations right now. He and Rosenhaus would be dealing from a position of weakness right now.
IF McGahee has a spectacular season this year, (over 2000 total yards) then we can expect to see some serious posturing going into the 2007 season. Rosenhaus though not well liked is no fool. He will not renegotiate from a position of weakness. Expect Willis to play this year as though this were his contract year, he will be motivated by the $ signs he sees at the end of that road.
