We can thank Johnny "Football" Manziel for that, as he led Texas A&M over Nick Saban and the then-No. 1 Alabama Crimson Tide in the Aggies' first season as a member of the SEC.
But his late rise to the top isn't the only major shakeup of this week's race rankings. Check them out:
1. Collin Klein, QB, Kansas State
Passing: 145-of-208 (69.7 percent), 2,020 yards, 12 TDs, 3 INTs
Rushing: 154 carries, 758 yards (4.9 ypc), 19 TDs
2. Johnny Manziel, QB, Texas A&M
Passing: 227-of-336 (67.6 percent), 2,780 yards, 18 TDs, 6 INTs
Rushing: 156 carries, 1,014 yards (6.5 ypc), 15 TDs
Why: If Texas A&M had somehow pulled off victories over Florida and LSU, there's no doubt that Manziel would be the hands-down favorite to win the Heisman. He's on pace to be the first 3,000/1,000 player in SEC history as a true freshman. If Manziel continues to put up numbers like this through his collegiate years, he'll be shattering NCAA records.
3. Kenjon Barner, RB, Oregon
Rushing: 199 carries, 1,360 yards (6.8 ypc), 19 TDs
Receiving: 18 rec, 218 yards, TD
Why: Barner's Heisman chances took a huge hit as he rushed for just 65 yards in Oregon's 59-17 win over California. The Ducks' entire backfield had a difficult time finding space, so it wasn't just him, but he's going to have to put up some wild numbers in the few games remaining to hold his positioning in the race.
4. Marqise Lee, WR, USC
Receiving: 98 rec, 1,447 yards (144.7 per game), 13 TDs
Rushing: 10 carries, 110 yards (11.0 ypc)
Why: The Trojans' woes have paid off in dividends for Marqise Lee's individual statistics. They're using his high-level versatility not only at receiver, but in the backfield and in some defensive situations. If USC reaches the Pac-12 title game, Lee is on track to finish with 2,904 all-purpose yards and 18 TDs — not including the postseason.
5. Marcus Mariota, QB, Oregon
Passing: 180-of-251 (71.7 percent), 2,164 yards, 28 TDs, 5 INTs
Rushing: 78 carries, 516 yards (6.6 ypc), 3 TDs
Why: This is one heck of a freshman quarterback class. Mariota, who has somehow been off the radar, is coming off an explosive game against Cal: the Honolulu native threw for 377 yards and six touchdowns while adding 42 yards on the ground. If you think this year's race is fun, just wait until next year.
Others to watch (in order):
6. Braxton Miller, QB, Ohio State
7. Manti Te'o, LB, Notre Dame
8. Tajh Boyd, QB, Clemson
9. Colby Cameron, QB, Louisiana Tech
10. Jordan Lynch, QB, Northern Illinois
