Using history as your guide no one should be surprised that a Venables (Stoops, Stoops, Leavitt) defense got torched by big plays and/or completely lost guys in the secondary. It's always been an issue in games like last night and it's just weird because their defenses can be so lights out and then Blam-O somebody is busting free or somebody is running wide open deep. While I have no real facts to back me up, it is my perception that this happens because BV (Stoops, Stoops, Leavitt) defenses try very hard to match-up personnel every play and sometimes that turns into a cluster.
It also didn't help that Clemson by the middle of the game was down another key defensive player and was missing two right from the opening kickoff.
