Putting all his eggs into the Nico basket and him bailing after spring blew this year up. Aguilar has been good but face it, he wasn't highly recruited for a reason. You've seen his offense with a really good QB (Hooker), it's awesome. As for the defense, if changes aren't made after this year, it will absolutely be his downfall. Even with injuries, there are no excuses. Being out of position constantly, awful tackling etc. The talent isn't THAT bad, maybe not elite, but nowhere near next to last in the conference bad.
