I wouldn't trade Epenesa now. Prior to this season beginning, I thought it was a possibility but his game appears to have risen. DE is a premium position and I would think Beane is considering re-signing him. Who knows if Miller returns to form, Floyd is on a 1yr deal as is Lawson. If the Bills can't re-sign Epenesa for whatever reason, he's likely to get a pretty big contract which could give the Bills a pretty good comp pick. I believe Beane will use whatever available cap space he has to re-sign guys. Probably no big name free agent signing.
