Didnt have anything to do with the rule change. Look at what ND has done twice this year. ( i know i will get ripped for that but its the truth) You are talking about Ole Miss after all. Its all about having a smart head coach that knows what he is doing.
It had a lot to do with the rule change. The time they lost when possession was changed, was time that they could have used to spike the ball or run another play.
