This might be off-topic, but why did Rich Rod struggle defensively in 2008? He probably had more talent on that roster than he was used to having at West Virginia, Rich Rod's 2008 defense, which had 8 returning starters, including future NFL guys Brandon Graham and Jonas Mouton, gave up 347 points during the 2008 season, whereas in 2007, the defense gave up 243 points. Was it all just because Shawn Crable, Chris Graham, and Jamar Adams graduated? I don't think the defensive breakdown in 2008 can be attributed to a lack of talent on the field.
I think Rich Rod's ability on defense is majorly in question after his record at Michigan. Right after he got to Michigan, the defense got way worse; right after he left, it's gotten way better. I see comments like "Rich Rod is the best coach out there with the exception of Urban Meyer" and I just don't really see it. Maybe he's one of the best offensive minds out there, but the record of his defenses at Michigan is terrible and cannot simply be explained by lack of talent on the field.
