I must have missed something. I thought an interpretation came out several years ago that said if a defender has a foot out of bounds it has to be a block. I think someone stated this and the rationale, but there has been a lot of back and forth about this in this thread. I hope we can all agree that someone running into a player that is talking to his coach is different than someone trying to actively play defense with a foot on the line.
Some people make it seem like we could apply WIF to the offensive player.
