As quickly as he was there, he was gone. Taylor Martinez was the only Big 12 player who's made my ballot the entire season, but the worst way to build Heisman buzz is to follow up your best game with one of your worst. He wasn't mistake-prone, but the Texas defense bottled him up and tackled well to keep him from breaking any lengthy runs. Facing Kansas State's defense is obviously different from playing Texas', but you'll be hard-pressed to find a Heisman candidate who's been benched, as Martinez was last week.
If he can put up a couple more 200-yard rushing days, he could become a factor again, but for now, he'll fall below four players on undefeated teams.
Oklahoma and Oklahoma State both have huge games on Saturday against Missouri and Nebraska, and huge games by anyone on this list might warrant some legitimate national Heisman buzz.
1. Landry Jones, QB, Oklahoma: Hard to ask much more of the sophomore, who completed 30 of 34 passes for 334 yards and three touchdowns before taking an early seat in the Sooners' 52-0 win over Iowa State.
2. Justin Blackmon, WR, Oklahoma State: It's almost impossible to win the Heisman as a receiver, but the fastest way to at least become a finalist is to keep averaging almost 200 yards receiving a game, as Blackmon has done the past two weeks. A tough test awaits on Saturday in a matchup with Prince Amukamara.
3. Kendall Hunter, RB, Oklahoma State: The formula is pretty simple. He leads the league in rushing, only two more players have more touchdowns, and his team is undefeated. Keep all those things going and he might enter the Heisman conversation.
5. Taylor Martinez, QB, Nebraska: One rough game doesn't erase his stellar performance leading up to it. He won't be facing athletes like Texas has every week, and the Longhorns are still one of just a handful of teams who'll be able to stop him like that.
Here's who I voted for in this week's Heisman Watch on ESPN.com:
1. Kellen Moore
3. Cam Newton
5. Andrew Luck
