Last night, the Miami Hurricanes defeated the Duke Blue Devils 30-27 on an insane 75-yard, 8-lateral return. The problem: it shouldn't have counted, for at least two reasons if not more. A flag for blocking in the back was actually thrown on the play against Miami; the replay officials overturned that penalty. It was actually correctly overturned; the problem was that the penalty in question wasn't reviewable.
Meanwhile, another block in the back -- this one, an actual block in the back rather than an incorrectly flagged one -- went unnoticed, and there's a very real question as to whether one of the involved Miami ball-carriers was down by rule before managing to get a lateral off.
