WR was the biggest FA need, only position that could not be filled via the draft.
The Bills need starting LG, DE, LB, TE....they can sign 2 through FA and draft 2 with the first two picks. I still think DE/TE will be through the draft, so look for the Bills to sign June/Peterson soon. They haven't had in any LGs right?
They COULD go 1) DE 2) LG 3) TE in the draft, that wouldn't surprise me.
