The bills only traded back because they thought their guy would be available at 2.01.
That tells me they want to take a guy that most people didn't mock in the first round. So who could that be ?
Is it possible the bills loved a guy like Ricky Pearsall, and thought no way someone would take him in the first?
What if the bills shot themselves in the foot?
Unless the bills trade down again, why risk losing out on your guy just to gain a better draft position in round 3?
