I think Ohio State will lose a few more games this year, they got crushed by the very same USC team that Oregon State beat.
They may well, but there's a history with the PAC-10/Big10 games that crossing the country matters...with few PAC10 teams beating upper half Big10 teams when playing in the midwest, even during that tremendous run the PAC-10 had in the 70s and 80s in the bowl games (occassionally facing and beating the very same team they'd lost to earlier in the year).
