A day after the top two teams in the AP Top 25 lost, the Buckeyes jumped two spots Sunday in the media poll and became the third school this season to hold the No. 1 ranking. "We've improved each week but we understand that the only poll that counts is the last one," Ohio State coach Jim Tressel said in a statement. The Buckeyes (7-0) beat Kent State 48-3 Saturday and have played only one team that's been in the rankings at any point this season. In a season in which 10 ranked teams have been beaten by unranked teams, just avoiding the upset bug has been enough for Ohio State. Ohio State was No. 1 last season from preseason until the final poll, when the Buckeyes dropped to No. 2 after losing the BCS national championship game to Florida. The Buckeyes received 50 of a possible 65 first-place votes, and were not the only team to advance. South Florida, which had never been ranked before this season, moved up three spots to No. 2, leapfrogging No. 3 Boston College. The Bulls received 11 first-place votes after a 64-12 victory over Central Florida. BC's workmanlike 27-14 victory over Notre Dame helped get the Eagles one first-place votes. No. 4 Oklahoma and No. 5 LSU each received one first-place vote, as did No. 12 Arizona State.
