I think the Bills will go with best player available, but there is one other thing that I am certain they will plan for. They will do what ever they have to, to buy more time for EJ and to find ways opening holes for our running backs. If a highly graded OLman falls to them, they will jump at the chance.
Of course, the way things are looking, the top 2 OLman are going to be gone. That is where things start to go a little fuzzy in the prediction department. They could go WR, TE, LB, DL or even QB. My thinking is that whoever it is, it will be someone that Whaley or Marone thinks will have the biggest impact improving the team.
