No, I noticed it too. It was a pick play. In fact, I thought two of their long TDs were pick plays. Technically it is offensive pass interference, but it rarely gets called. UCLA was doing it too.
Offensive pass interference just does not get called anymore, in college or NFL, as it is defined. 10 years ago-heck, maybe even just 5- that gets called in a heartbeat. I think it's one of them things that gets turned away from in order to support this age of offense. Let's face it. Offensive players-esp in the NFL-have numerous advantages rules-wize. I think this is becoming another.
Yep.... the rules are as offensive-skewed as they've ever been, at least in my lifetime. They'll throw DPI on almost any sort of contact these days. Holding has to be blatant to get called. All borderline hits on quarterbacks are called.
So yeah, it is a much tougher climate to be a defensive coordinator than it was 20 years ago.
