USC's win is obvious. The Trojans have accounted for 111 Pro Bowl berths. The Bulldogs 47. It is notable, however, that from 1990-99 Georgia nipped USC -- in the ESPN.com point system -- 43-42. The Trojans were clearly superior in the decades before and after.
It won't be surprising to UCLA fans that the Bruins' recent history brought them down. UCLA didn't rank in the top 34 from 2000-2009; Pittsburgh was 18th during that span. The Bruins' strength was the previous two decades. They ranked 11th from 1990-99 and fifth from 1979-89.
