Penn State scored touchdowns on seven straight possessions against USC in the Rose Bowl. People forget that.
To be fair, some of the 4 straight plays thing was luck and turnovers.
Not denying that USC played terribly in there on defense for a while, but they endured a lucky ass catch by God (win), one ridiculous scrambling play/throw by McSorley that wasn't actually a catch but was still called a TD, got shafted by the refs several times, and also sucked for 3 quarters.
Lots of factors contributed to that, the main one of which was USC
crapped the bed sucks and barely beat an overrated PSU team.
