Fitz the businessman should ask himself whether (1) he will get a better deal elsewhere, and (2) he will start anywhere else.
If he really thinks that he can get a better deal elsewhere, he should probably play somewhere else.
The fact of the matter is we signed him at the apex of his market value. Unlike some players, he has not played up to his contract. He should be thankful for the millions that he did get and that the Bills did not wait until the end of the 2011 season to sign him.
