The problem with this is the Bills do not need to address the loss of Gilmore until it actually happens. Even if they decide to let him walk next year, they do have him this year, and they have real needs at DL and LB. it makes no sense to draft a Gilmore replacement at this point. Perhaps the Bills will see it your way and select a BPA, if he actually is at that point, rather than fill a need, but I doubt it. If that were the case, they would probably try to trade down.
