Well the time of possession hasn't even been 30+ and the offense has remained at or near the bottom of the Big 12 in scoring, I think the DC is maybe one of the last people to blame behind the OC and HC. It felt like the defense was out on the field a lot last year and the TOP was 27:16 or last in the Big 12. The TOP is currently better than it has been, but that might be a product of some of the teams having a quicker offense than last year. We certainly aren't scoring anymore than last year. KSU which we can agree is a ball control team has the ball 32+ minutes a game. So, I think there is a little more disparity on TOP than you might think.
The other thing is that we knew there was some inexperience on the defense, but when they are on the field playing their risk of injury increases. When a player goes go down with an injury the next guy in probably does not have as much experience and/or coaching as the starter. If the injury is serious and the starter is out for several games then we lose some of the cohesion of the defense.
