Seriously though. They'll follow the same protocol as your CB's and safeties do... the way you set them. They have to pass a vision check to recognize any play different than what you set them on (if you told them to cover a WR, they'll cover until they "see" it's a run play, then react accordingly). not true, bort did say in the past there was a significant penalty for LB's covering WR's but he didnt specify what... best thing is only do it if you are setting it as a 2nd man or a 2nd option on the WR
ie, HB or WR1, but dont make the LB straight up vs WR as the only guy covering... and im pretty sure the penalty is only in the coverage part of his asignment
