I’ve been re-watching Super Bowl 43 on the treadmill. On James Harrison’s int return for a TD, which was arguably the greatest play in Super Bowl history (top 3 for sure), it was almost for not because Larry Legend ran out of bounds for 40 yards to make the tackle. If the tackle was on the 1 foot line instead as time expired, what would have happened? What’s the rule? Would that have been a defensive penalty and therefore not end the half? Would they have backed the ball up 15 yards for one final play? Would running out of bounds for 40 yards essentially saved the Cardinals 4 points on the scoreboard?
