The controversial ending to Saturday's game between Western Michigan and Michigan wouldn't have happened under NFL rules. According to Rule 15, Article 9(b) of the NFL rulebook, an on-field ruling that time expired during or after the last play is only reviewable when visual evidence demonstrates the clock should have stopped with two or more seconds remaining. esporist.com
The Michigan controversy centered on whether the clock showed one second or no time remaining when a Western Michigan player touched a Hail Mary attempt that sailed out of the end zone. The Big Ten's ruling gave Michigan a 'mulligan' in this situation, but under NFL rules, the game would have ended with Western Michigan's interception standing as the final play.
