correct me if I'm wrong but shouldn't that then become a penalty on defensive player? I thought once you go out of bounds, you cannot touch the ball? If a receiver steps OOB at some point running his route, he becomes ineligible and a flag is thrown if he does catch a pass. So although it would probably still be ruled a dead ball, at least they should have gotten the penalty yards.
Or do I have this all wrong?
I remember that Bills game as well and was asking this same question then.
