First, maybe the Bills didn't like Moore, and were looking at other options that either retired or re-signed elsewhere. Second, Moore might have put the Bills in a bidding war solution, and the Bills preferred to just get someone who is locked up (kinda like McCoy for Kiko, instead of going after Murray). Third, the Bills might have identified Cassel as part of a group of QBs that would be better in the QB room with EJ for mentoring purposes. We really don't know exactly what trading two picks for Cassel and another pick was about. In the end, it effectively didn't cost us much. I think if the Bills were truly desperate to get away from EJ, they would have cut him, like Leroi suggested.
