I don't think I'm right.. by what was 'said' about that interference last by the announcers, refs, and what was posted on the board. For whatever reason I also thought interference COULD be called if it took place before the 'tip'... which last night may have been the case. However... in all the explanations I read following that call not a thing was mentioned about that. IOW... you could maul a receiver directly off the line and as long as you tip the ball during the play = 'no interference'. - JamesJM
