One of TD's first moves as the new Bills GM was deciding between re-signing Marcellus Wiley or Eric Moulds. Both were pretty young and coming off good seasons, but only one could be re-signed, because of the cap mess Butler left, and TD chose Moulds. Had Cowart not suffered the Achilles, and given his age and the improved cap status, I think the Bills/TD would have re-signed him. In the case of Winfield, although he was good and young, the Vikes were offering him mad money (I believe he received an $8M roster bonus) and the Bills didn't believe he was worth it.
