NFL rules would've denied Michigan's Hail Mary

According to Rule 15, Article 9(b) of the NFL rulebook, a play after time expires is only reviewable if visual evidence shows at least two seconds remained on the clock. In the Michigan game, it was unclear whether one second or no time remained when the Hail Mary was touched.

The Big Ten ruling gave Michigan a 'mulligan' in a situation that would have ended differently in the NFL. This highlights key differences between college and professional football clock management rules. zeppelin.cool
