I think last night was just a perfect storm of bad circumstances all adding up. Somewhat similar to USC 2016, actually.
-Offense was slightly off (but did enough to win, barring Hooker's injury)
-Quite likely some truth to the Banks rumors, so our already bad defense may have been checked out or discombobulated
-Rattler played damn near perfect
-Refs were letting USC get away with a lot of holding and nailed us on some iffy penalties
-Gamecocks started red hot and had momentum for virtually the entire game, creating a hostile environment that our team wasn't expecting
-Coaches and players likely overlooked USC to a degree
Rattler playing perfect is probably the biggest factor, to be honest. Even with everything else going on, we still win that game if he's average and misses some throws. But he was Mahomes out there.
