FWIW, here is a mock draft from CBS Sports that came out today. They have the Bills trading down with Washington whereby the Redskins take Oklahoma QB Kyler Murray at #9 and the Bills take Florida OT Jawaan Taylor at #15 plus the Bills receive Washington's 3rd & 5th Round picks in the process.

15. Buffalo Bills (via MOCK TRADE with Washington)
Jawaan Taylor, OT, Florida. The Bills move down and are still able to get a franchise right tackle -- yes, they're a thing now -- in Taylor, a large, nimble, and powerful blocker who'll start immediately. Buffalo gets Washington's third and fifth-round picks in the trade.
