I agree, I don't see the Bills going OT in round 1. Nothing they have said or done would suggest it, but it's the route I'd like to see them take.
If the draft played out the way you mocked it, I would hope they would trade up for Addison, or trade down and take the best WR OL MLB available. Hyatt at 27 would be disappointing to me. Don't see how a situational player in Rd 1 gets us over the hump.
