My view is that it isn't as bad as it looked. That said, the most glaring flaw I see is a lack ability to adjust when your plan doesn't work. Our plan was fantastic against UNC. Today, our plan underestimated the lineman of Pitt on both sides. That happens, but this staff didn't seem be able to adjust, at least not meaningfully(dropping 8 in the 2nd half down 28 is surrender, not adjustment).
Pitt is one of the dirtiest teams in the ACC. If Saban was coaching, he'd figure out to a way to get more calls. Part of being a good coach is being able to get penalties by teaching players to make penalties more obvious, at an extreme its called flopping. We acted surprised they held us. We made mental errors. We stopped covering WRs at the end of their routes. We had a TE shake and bake one of our starting DBs. We played like crap as a team with a strategy.
I'm not ready to give up on CGC, but its hard not to see a him as a guy with more focus on social media than X and Os. His critics might be wrong, but they aren't blind.
