1. Oklahoma (pre-spring ranking: 1): The Sporting News has listed the Sooners as its preseason No. 1 team in the country, due in large part to Oklahoma’s offensive line. That might be going overboard, but the Sooners have a wealth of experience and depth returning up front, which includes four starters. They’ll get even deeper once guard Tyler Evans is cleared this summer, as expected (he was running this spring). Evans has missed the past two seasons with knee injuries but was a three-year starter before getting hurt.
After losing both offensive tackles from last season, Kansas State is switching All-Big 12 guard Cody Whitehair to left tackle.
2. Kansas State (2): K-State responded to losing both tackles from last season by swinging All-Big 12 guard Cody Whitehair to left tackle and slotting juco transfer Luke Hayes at right tackle. With B.J. Finney entering his fourth year as the starting center and more juco offensive line help arriving in the summer, the Wildcats should be more than solid up front.
3. Texas (3): The Longhorns will feature one of the eldest lines in the Big 12, with its projected starting front comprising two seniors and three juniors. Right guard Taylor Doyle emerged this spring at the biggest question spot, but Texas has other options inside with Rami Hammad, Curtis Riser and the versatile Kent Perkins. Center Dominic Espinosa is the anchor of this group, which will be asked to establish itself with the running game in Charlie Strong’s first season.
4. Baylor (4): The Bears are still waiting for left tackle Spencer Drango to return from last season’s back injury, but right tackle Troy Baker showed no lingering effects of the knee injury he suffered last spring. With the depth inside and with Kyle Fuller locking up the center job, there are no weaknesses with this cast -- provided Drango gets healthy and gets back to the field.
5. Oklahoma State (5): The Cowboys are also waiting for their left tackle to return from an injury he suffered last season. Devin Davis has NFL potential but has been slow to recover from an ACL tear last preseason. The Cowboys seemed to also be in a fix at center with their top-two players at the position from last fall moving on from the program with eligibility still remaining. But Paul Lewis slid over from guard this spring and stabilized that spot. Daniel Koenig is an All-Big 12 caliber player and capable of playing tackle or guard. He’ll continue to man left tackle, at least until Davis returns.
6. Texas Tech (6): Tech received some welcome news during spring ball with starting right tackle Rashad Fortenberry being granted an extra year of eligibility. The Red Raiders have one of the best returning tackles in the league on the left side in Le’Raven Clark, and two juco tackles they’re high on in Shaq Davis and Dominique Robertson. With Jared Kaster and Alfredo Morales also returning as starters inside, Tech’s offensive line should be much better than last season's.
7. West Virginia (7): The Mountaineers have the league’s most reliable one-two punch at guard in Quinton Spain and Mark Glowinski, who have 38 career starts together. The rest of the line, however, is a question. Left tackle Adam Pankey impressed coach Dana Holgorsen early in the spring and won a starting job before the Gold-Blue Game. If Pankey pans out, the Mountaineers could be a load up front.
8. Iowa State (8): The Cyclones had disastrous luck with the health of their offensive line last season, but that should pay off in 2014 with so many different players having gotten experience. Left tackle Brock Dagel has immense upside, and center Tom Farniok is an All-Big-type player. But the Cyclones were especially pumped with the development of sophomore right guard Daniel Burton, who is physical and one of the smartest players on the team. If they get better luck with good health, this could wind up being a very a tough and balanced unit.
9. TCU (9): The Horned Frogs welcomed the return of tackle Tayo Fabuluje, who left the team before the start of the season last fall. Fabuluje, however, missed several practices with an ankle injury, allowing redshirt freshman Joseph Noteboom to move ahead of him on the depth chart. Fabuluje will have a chance to earn his spot back in the spring opposite Halapoulivaati Vaitai, who replaced Fabuluje last season. But the way the 2013 season went, the Horned Frogs can’t have too many reliable offensive tackles. Juco transfer Frank Kee impressed during the spring and should lock down a starting spot at guard next to center Joey Hunt, who did a nice job of adapting to the new offense during the spring. With 6-foot-7, 350-pound Matt Pryor also likely to fit in somewhere in the rotation, the Frogs will definitely be bigger up front than they were in 2013 -- and probably better, too.
10: Kansas (10): Because he can get in and out of the pocket, Montell Cozart winning the starting job should help the offensive line. The fact that new offensive coordinator John Reagan is also an offensive line coach should be a boost, as well. The Jayhawks have several battles up front that will continue into the fall, including center, where walk-on Joe Gibson made a huge impression during the spring.
