You're going to get a range emotion on this subject. I'm going to try and be as factual as I can, and just say that he wasn't ready for his promotion to Co-DC.
I get what Miles was trying to do, maintain continuity on defense at a time when he was preparing for a BCS title game. Pelini got the Nebraska job after the season was over, and Miles chose to promote from within and concentrate his efforts on the BCSCG, rather than conduct a search for a new DC. It didn't work out.
LSU's defense in 2008 fell to 11th in the SEC, despite the fact that LSU returned a lot of the players from the second-ranked SEC defense in 2007 and all the defensive coaches save Pelini. In 2007 LSU gave up 19.6 ppg. In 2008, the Tiger defense gave up 25.9 ppg. Since Chavis became DC, we've never given up more than the 17.8 ppg in 2010. Take out 2010 and we've averaged about 16 ppg.
The main problems with the Co_DC's were that they tried to "min-max" on every play...I.E. get what they thought were the best players in for each down. The result was that LSU defenders were usually confused and out of position on every play.
After the 2008 season, Miles chose to clean house on defense. Rather than being fired, both Peveto and Mallory landed jobs at other schools.
As a position coach, Peveto is liked by his players, and brings a lot of passion and energy to his job. Your players will be motivated, no doubt.
Wish both BDP and UK luck with this.
