Game was at Autzen, right? PAC-10 officials? If so, that explains the bad officiating.
PAC-10 officials are well known to be the worst in the country. So bad that a few years ago, during the bowl season when the officials are not from either of the two conferences playing in the game, the announcers were questioning a call made by the PAC-10 crew and they stated that the PAC-10 officials are known for blowing calls. PAC-10 officiating sucks, plain and simple.
