More horrible clock management on that last LSU drive. They are anything but a quick strike team, yet they were continually screwing around at the line and letting the play clock run all the way down, even when it got below 2 minutes left and they only had 1 timeout.
Even if he hadn't thrown the INT they were probably going to end up having to settle for a 50+ yard FG. Have seen this from Les Miles many times before.
