From the Washington Post:
"As far as an indication of how Ohio State might do, the preseason poll isn’t always a good omen. The Buckeyes were the No. 1 preseason pick in 1998 and 2006 and both times finished second nationally. The last team to win the national title after being ranked first in the preseason poll was USC in 2004 and the Trojans’ championship was vacated because of NCAA rules violations. The only other team to be ranked No. 1 from the preseason poll through the national championship was Florida State in 1999."
