1. Oklahoma (pre-spring ranking: 1): While the future of inside linebacker Frank Shannon remains unclear, the Sooners have a tailor-made replacement in Jordan Evans ready to go. Shannon was OU’s leading tackler a year ago, but Evans was the defensive MVP of the spring game in his place. Blitzing outside linebacker Eric Striker had a huge spring coming off his three-sack performance in the Allstate Sugar Bowl. And the Sooners had another blitzing linebacker in juco transfer Devante Bond emerge in March, which could give them flexibility to move Striker around. Dominique Alexander, the reigning Big 12 Defensive Freshman of the Year, solidifies OU’s perch atop this positional ranking, even with Shannon’s future in limbo.
2. Texas (2): Steve Edmond sparked controversy with his Baylor comments, but he also impressed coach Charlie Strong this spring with his knack for making tackles. Edmond and Dalton Santos team up to give the Longhorns a reliable combination on the inside. Athletic sophomore Timothy Cole took advantage of his opportunities with the first-team defense during the spring but should fall back into a spot role once Jordan Hicks returns this summer from a second consecutive season-ending injury. This will be a good group of linebackers, but Hicks playing up to his five-star potential is what could make it great.
3. West Virginia (3): After struggling at the “Spur” linebacker spot in 2013, Isaiah Bruce moved back inside this spring, where he starred as a freshman All-American two years ago. Bruce said he didn’t feel as comfortable playing outside and that showed, as he didn’t record a sack last season despite playing off the edge. Taking over in the Spur is converted safety K.J. Dillon, who was as impressive as any West Virginia defender this spring. With the ability to drop back in coverage, attack the run and rush the quarterback, Dillon seems to be a much better fit at the Spur. If he continues to progress at his new spot and Bruce gets back to his old self playing alongside tackling machine Nick Kwiatkoski inside, the Mountaineers will be stout at the second level.
4. Kansas (5): If the Jayhawks finally climb out of the Big 12 cellar for the first time in six years, it will be on the back of Ben Heeney and a Kansas defense that returns nine starters. One of those nine returners is Heeney’s linebacker wingman, Jake Love, who delivered a strong spring game with a scrimmage-high 10 tackles. The Jayhawks have several weaknesses, but the tackling of their linebackers is not one of them.
5. TCU (6): They get overshadowed by the units in front of and behind them, but linebackers Paul Dawson and Marcus Mallet simply fulfill what’s asked of them. The Horned Frogs were surprisingly solid at linebacker last year. They should be even better in 2014.
6. Texas Tech (7): The Red Raiders received a huge boost in the spring from Kenny Williams, who made a seamless -- and voluntary -- position switch from running back to the “Raider” linebacker position. With honorable mention All-Big 12 pick Pete Robertson on the other outside spot and veterans Sam Eguavoen and Micah Awe and Utah transfer V.J. Fehoko manning the middle, the Red Raiders have a solid foundation. Ex-Ohio State linebacker Mike Mitchell, who attended Tech’s spring game, could give the unit another boost in the summer. He was an ESPN 300 recruit last year and could be eligible immediately at his next school.
7. Kansas State (8): Coach Bill Snyder seemed to be reasonably pleased with returners Jonathan Truman and Will Davis, who have locked up two of the linebacker spots. If D'Vonta Derricott, who was in the ESPN Junior College 50 and had offers from Miami, Wisconsin, Arizona State and a host of Big 12 programs, can make an impact at the third linebacker spot, the Wildcats could quickly solidify their biggest question spot defensively.
8. Baylor (4): Middle linebacker Bryce Hager will be fine once he finally recovers from a groin injury. That means Aiavion Edwards, who exited spring as the starter on the weak side, will be the key as the Bears attempt to overcome the graduation of All-Big 12 performer Eddie Lackey. Baylor, though, still has big expectations for juco transfer Grant Campbell, even though he finished spring as a backup on the depth chart. After a shaky first few practices, Campbell began to come on late in spring drills.
9. Oklahoma State (9): The Cowboys picked up a valuable transfer during the spring in former Michigan safety Josh Furman, who will be eligible immediately after getting his degree. Furman isn’t a star, but he has plenty of experience and could be a real asset teamed with juco transfer D'Nerius Antoine at Oklahoma State’s “Star” linebacker spot. On the weak side, fellow juco transfer Devante Averette really shined before suffering some mild injuries at the end of spring ball. The Cowboys will be even better there if 2012 four-star signee Seth Jacobs emerges.
10. Iowa State (10): The Cyclones remain in transition mode at linebacker while working to replace the production of departed All-Big 12 performer Jeremiah George. Redshirt freshman and former QB Alton Meeks was one of the defensive surprises of the spring; he currently sits atop the depth chart at middle linebacker. The other big defensive surprise was walk-on senior Drake Ferch, who beat out returning starter Jared Brackens on the strong side. Jevohn Miller is the third starting linebacker, but he figures to be a placeholder on the weak side until Luke Knott returns from last year’s season-ending hip injury.
