I can help but thinking the two instances are somewhat related.
From the time they (USC) left the tunnel there was a concerted effort to "intimidate." Before the game the talk was how they could be physical and stand toe to toe. But, as time ran along ...
Those efforts to be physical turned into something else. It's not the first time we, as fans, have seen teams do this when playing Bama.
Herbie had it right minutes later ... Karma.
