Big 12 Heisman Watch: Week 4

Landry Jones made some key throws in a huge game against Florida State, but for now, I couldn't in good conscience keep him ahead of a quarterback doing the kinds of unspeakable things to defenses that a certain passer in Waco is doing.

1. Robert Griffin III, QB, Baylor

Last week: 20-22, 265 yards, 3 TD in a 48-0 win over Stephen F. Austin.

Making the case for Griffin: Griffin was the biggest reason for his team's season-opening win over then-No. 14 TCU and after three quarters of work in an abbreviated blowout over the Lumberjacks, has eight touchdowns and eight incompletions through two games, and has Baylor ranked as high as it's been in two decades.

2. Landry Jones, QB, Oklahoma

Last week: 18-27, 199 yards, TD, 2 INT in a 23-13 win over Florida State

Making the case for Jones: I believe Jones just faced the best defense he'll see all year, and he got the job done, making the big throws when he needed to make them. I wouldn't worry too much about the modest numbers, which will return to Heisman numbers when he's not busy beating top 5 teams on their home fields.

3. Cyrus Gray, RB, Texas A&M

Last week: 29 car, 101 yards, TD in a 37-7 win over Idaho.

Making the case for Gray: Business as usual for Gray, who stretched his streak of 100-yard rushing games to nine. The same was true for the Aggies, who will need a big game from Gray to move to 3-0 when Oklahoma State comes to town on Saturday.

4. Brandon Weeden, QB, Oklahoma State

Last week: 29-39, 369 yards, 3 TD, 2 INT in a 59-33 win over Tulsa.

Making the case for Weeden: Weeden had to deal with a three-hour delay in Saturday's game, but he's filling up the stat sheet in every way possible. He's the nation's leader in passing yards, attempts and interceptions. He's also eighth in completion percentage and 11th in touchdown passes, with eight on the year.

5. Ryan Tannehill, QB, Texas A&M

Last week: 26-39, 337 yards, 2 TD, INT

Making the case for Tannehill: Tannehill did what he needed to do against the Vandals, too, but we may see some big movement in these standings on Saturday, when three of the Big 12's top five Heisman candidates are in the same stadium.

Finally, here's what my ballot looked like in ESPN's weekly Heisman Watch:

1. Andrew Luck, QB, Stanford

2. Robert Griffin III, QB, Baylor

3. Kellen Moore, QB, Boise State

4. Marcus Lattimore, RB, South Carolina

5. Landry Jones, QB, Oklahoma
