Over the next two weeks, we'll be unveiling the 10 best players on every Big 12 roster. We won't be including junior college or freshman signees who have yet to arrive on campus, as we're only looking at players with their teams this spring. These lists are sure to change, but this is how we see them now.

We begin this series with the Oklahoma Sooners:

1. QB Baker Mayfield: Mayfield twice has finished in the top five of the Heisman voting. He has quarterbacked the Sooners to back-to-back Big 12 titles. And last year, he broke the FBS record for passing efficiency in a season. As Oklahoma's starting quarterback, Mayfield is 17-1 in Big 12 play, with a staggering 65 total touchdowns.

2. OT Orlando Brown: Brown has started 26 straight games for the Sooners and is now the reigning Big 12 Offensive Lineman of the Year. Brown, who was also a second-team Associated Press and Football Writers All-American, is a load in the running game and a difficult obstacle for any edge-rusher trying to get to Mayfield.

3. CB Jordan Thomas: Thomas had a bit of an up-and-down junior campaign. But when locked in, he's still one of the best cover corners in the country. Being a four-year starter will make Thomas one of the country's most experienced corners, too.

4. LB Ogbonnia Okoronkwo: Okoronkwo finished third in the league last year with nine sacks and fifth with 12 tackles for loss. He is a relentless pass-rusher and should improve in his second season as a full-time starter.

5. TE Mark Andrews: With Dede Westbrook gone, Andrews figures to take on a larger role within the passing offense as the Sooners' top returning receiver. Andrews is also a terrific edge-blocker and once again will be pivotal in Oklahoma's power-rushing attack.

6. FB Dimitri Flowers: Though unheralded, Flowers is also a key piece in the offense as a blocker. However, he is capable in other ways when needed. He caught four touchdown passes last season, and when Samaje Perine and Joe Mixon were both out, Flowers rushed for 115 yards on 22 carries in a weeknight road win over Iowa State.

7. OG Ben Powers: After Cody Ford suffered a season-ending injury in Week 3, Powers stepped in at left guard and delivered a terrific season on the way to earning honorable-mention All-Big 12 honors. With Ford back, Powers is now in a battle just to keep his starting job, underscoring the depth the Sooners will have up front next season.

8. S Steven Parker: Like Thomas, Parker had a bit of an uneven junior season. He was still an honorable-mention All-Big 12 selection, and he still has the talent to be one of the conference's top safeties.

9. LB Caleb Kelly: Don't be surprised if Kelly isn't one of Oklahoma's best players by the end of next season. As a true freshman, he eventually worked his way into the starting lineup before breaking out in the bowl game with 12 tackles in the victory over Auburn.

10. RB Rodney Anderson: Anderson is coming off a pair of season-ending injuries (neck, leg) and has only one career college carry to his name. But coaches and teammates have been raving about Anderson's potential for years. Now healthy again, he'll have every opportunity to take over as Oklahoma's primary ball-carrier with Perine and Mixon gone.
