A change at the top this week after Baylor's season saw its first loss.
Let's take a look at how the Big 12's Heisman candidates might look if voting took place today.
1. Landry Jones, QB, Oklahoma
Last week: 23-33, 425 yards, 5 TD, INT in a 62-6 win over Ball State.
Making the case for Jones: Jones has been steady and is putting up numbers indicative of a Heisman contender. His campaign will either hit a huge bump or boost on Saturday when he meets Texas in the Cotton Bowl for the third time in his career, a game that Sooners' success within can define their individual careers.
2. Robert Griffin III, QB, Baylor
Last week: 23-31, 346 yards, 5 TD, INT in a 36-35 loss to Kansas State.
Making the case for Griffin: Griffin is far from out of the race. He'll still have plenty of chances to inject himself back into the thick of it when he plays former Big 12 South opponents. His lone interception of the season came when he was hit as he threw, a bit of a fluke play. He had a chance late to rally his team on a game-winning drive, though, and didn't do it.
3. Brandon Weeden, QB, Oklahoma State
Last week: Chilled at home while his coach served as guest analyst for ESPN.
Making the case for Weeden: Weeden's Heisman buzz will hit its crescendo late in the season if the Cowboys keep winning and reach a showdown against Oklahoma on Dec. 3 undefeated. His numbers will be there.
4. Ryan Broyles, WR, Oklahoma
Last week: 4 rec, 109 yards, 2 TDs in a 62-6 win over Ball State.
Making the case for Broyles: Broyles had a historic Saturday night, writing his name down as the Big 12's career leader for receptions with plenty of time to catch a few more. He needs one more touchdown and 509 more yards to become the Big 12's career leader in those categories, too.
5. Justin Blackmon, WR, Oklahoma State
Last week: Off.
Making the case for Blackmon: Blackmon won't see his stock change much this weekend against Kansas, but like Weeden, his Heisman hopes will rise with OSU's win total.
Finally, here's what my ballot looked like in ESPN's weekly Heisman Watch:
1. Andrew Luck, QB, Stanford
2. Trent Richardson, RB, Alabama
3. Russell Wilson, QB, Wisconsin
4. Kellen Moore, QB, Boise State
5. Landry Jones, QB, Oklahoma
