Detroit is screwed. They are going to lose Suh and Fairley.
If a team gives Fairley more than a 2 year contract he is going to get fatter and will continued his injured ways. Out of four seasons he has only started more than 8 games once and never played a full season.
Suh is going to end up murdering some QB before his time in the NFL is up. I don't think he can keep playing after that happens, although Ray Rice kept playing so anything is possible.
