There were two central issues:
First, we got significantly out-coached. That manifested itself a lot of ways, but the bottom line is that Clemson was better prepared, and we never adjusted to take advantage of what their adjustments gave us. That's 1000% coaching.
Secondarily, when the D as a whole, and the secondary in particular, got punched in the mouth, they responded poorly, up to and including Clemson MTAQ.
Dabo took several pages out of The Process, and used them against us. Kudos to him and his staff. Now it's up to us to make sure that [stuff] never happens again.
