After a few weeks as little brother, LSU leapfrogged former #1 Alabama to take control of the #1 spot in the nation thanks to a 31-28 win over #10 Florida in the Swamp.

The Tigers are one of a large grouping of unbeatens in the NCAA in mid-October, with 15 teams without a loss thus far. The biggest surprises are #10 NC State (6-0), #15 Kansas State (5-0), #21 Pittsburgh (6-0), and unranked Illinois (6-0).

The Wolfpack have been led by QB Mike Glennon, the nation's second leading passer, and have been fond of pulling off tight victories. They escaped Wake Forest 28-25 in their second game, and also beat Cincinnati, 14-7, and escaped then #13 Virginia Tech in Blacksburg with a 13-10 win. Their biggest remaining tests are #25 Florida State on the 29th and at 5-1 North Carolina the next week.

For the Wildcats, star HB Bryce Brown has been sensational in their run, with 12 touchdowns on the ground and a 153.4 yard per game average. If the 'Cats make it to 7-0, they will be tested in a grueling stretch against #5 Oklahoma, #7 Oklahoma State, #18 Texas A&M, and #17 Texas.

Pitt has been a big surprise, making a strong transition to their new coaching staff. While the new offense has struggled at times, HB Ray Graham has been the constant that has pushed them to some big wins. Every team on the Panthers' remaining schedule is .500 or better, starting with #24 Utah (4-2) and last year BCS bid recipient UConn (5-1), and the Backyard Brawl will certainly be tough as well against West Virginia (4-2).

The least exciting of these unbeatens is the Illini, who have not played anyone noteworthy and have to prove that they can stay without a loss as they head to the Horseshoe to face an Ohio State (4-1) squad that blasted then #10 Michigan State 52-7 in their last game.

#20 Central Florida (5-0) is also unbeaten and with a schedule with only two teams with winning records remaining, may end up running the table in Conference USA.
