Several of the Farmer's opponents in the recent years have a offensive play that causes me anguish everytime they run it because it seems to be pass interferrence. They line up with 3 receivers out wide and one receiver steps back at the snap while the other two go forward and block the defenders. The QB throws a pass to the receiver that stepped back. So why isn't this offensive pass interference on the blocking receivers who are blocking the defenders before the pass is even thrown? I understand if the receiver moves far enough back for the pass to be a latteral then blocking is allowed but this isn't the case. I discussed this with several people lately and have gotten several different answers. In my opinion it is a blatant illegal move and some teams get away with it all the time. At times the blockers go 10 yards to block the defenders while the ball is in the air!
Any insights?
