I don't think you read my message carefully. I'm NOT suggesting he CHOOSE to not be a valuable commodity on the FA market. That would be foolish. What I AM saying that an INJURY might make that a reality. Let's say he has a great year, but gets injured in week 16 -- serious enough to harm his FA value. If he has a long-term contract with the Bills and can be healthy again the following season to play, then he is protected. If he gets hurt, teams will take a chance on him, but maybe not at the price they might have if he was 100% healthy. The choice Greer has is to take that risk. Then again, we don't even know if the Bills are talking with him anyhow, so it may be a moot point. He could agree to an extension with the Bills for just SLIGHTLY less than he might get as a FA and then not have to worry about staying healthy this year. Injuries are a reality of the game and players must take this into consideration at all times.
