I watched parts of, or an entire quarter or two of the Maryland, Memphis (both games), Austin Peay, SMU, Temple, & USF. Then the entire Auburn/Peach Bowl game.
The defense plays fast and aggressive and forces turnovers, unfortunately the USF and 2nd Memphis game wrecked their defensive stats. Prior to those two games UCF had been in the top 30 in many defensive categories. I think the wear & tear of the season with no bye weeks wore UCF's defense down.
Against Auburn I think the defense did a great job considering Auburn was a potent offensive team on the ground and through the air. What was most impressive was how UCF shutdown Auburn's run game. Auburn had 44 rush attempts and didn't even crack 100 yards.
One thing to also keep in mind against Auburn, Milton was not handling that big stage well in the first half and you know it's bad when teammates are on the sidelines when he'd come off the field to talk to him and try to calm him down. He missed a lot of plays that would have gone for TD's, setup TD's, or greatly extended drives and it's wasn't because of anything Auburn was doing, Milton was just flat out off. Milton being off, just gave Auburn the ball back that much faster and allowed them to gain more yards and points than I think they normally would have if Milton had been firing on all cylinders.
