I'll give credit to the coaches, they've done a good job considering the amount of youth and a lack of talent at some positions. Diaz has been great. He calls an aggressive game and forces the other team's quarterback to have to make plays to beat you. His work with three freshmen linebackers has been notable too. Quarterman, in particular, seems to have really gotten it and is rarely out of position. His tackling technique is also very solid. Rumph has taken a group of corners, who were essentially "Corn Elder and a bunch of other random guys" and made them formidable. They're not lights out and there's still occasional coverage breakdowns but overall they've been good. To be honest, I'd say the coach I'm most disappointed with on defense is Kool. Yes, sacks are way up and the line is overall much imporved but I still see them really struggle to pressure the quarterback with the front four. A majority of the sacks come on blitzes which is great but I'd still rather be able to get consistent pressure with the down linemen and against P5 teams, they're just not getting it done.
