Also- look at the teams you've lost to- two 4-0 teams, one team with A prestige.
My $.02 from an average at best coach- you can't have as many guys as you do with DE ratings below 30 in man to man. Also on D sets- you are running a combo D- Press/Man, and your press IQs are low- that will hurt a bit on the defensive end.
This is purely my opinion, and as I said, I'm average- I would give Null PT at the point. He's your best passer as a Freshman, second in BH, and assuming that he has decent potentials, you could have him as a solid player off the bench by conference season.
