The push actually doesn't happen as often as you'd like to think it does because when the QB is in the pile of players and the pile is moving, it's not a penalty. Not very often does the QB get stuffed spin to his side and get a two handed push to the chest. You admit it was a missed call. What difference does it make how often it's called? A rule is a rule and one of the higher ups in terms of NCAA Football officiating said it should've been a penalty.
The spot... I can live with the spot.
Another penalty had to do with Pete Carroll's son, and Assistant Coach, was down by the goalline calling for a timeout. Not only did they have no timeouts, but being by the goalline, he was obviously WELL outside of the coaches box.
Both penalties... neither called.
As for the fumble in the OSU game -- it was a turnover, but like I said, it was a FORCED turnover. He didn't just drop the ball.
USC won by 3. The Notre Dame kicker, Fitzpatrick, shanked a very makable FG not long before USC's final possession. Really... is that any different than OSU fumbling?
