We have positions like WR, CB, FS that are huge NEEDS. LB would be nice to upgrade but isn't on the level WR CB FS, and even pass rusher. I would take the BPA that is a position of need, unless someone amazing falls into your lap. I mean if you trade down in the first to pick up another 3rd and Teo fell to later in the round, (which is going to happen) then maybe you couldn't turn him down, but if we stay at the same position, you have to take the BPA at a position of need.
I add "at a position of need" because you don't take the BPA just because he is the best. If a GREAT Center, DT, RB, or punter falls to 13 you don't take him, because we don't need him.
