ESPN Senior Coordinator of Recruiting Jeremy Crabtree first noted it on Twitter on Tuesday morning. “The biggest recruiting rivals in Big 12 now? No, it’s not UT-A&M,” he wrote. “Try OU and Mizzou. Some great battles between Sooners and Tigers in 2012.” Oklahoma took the first major battle, grabbing a commit from St. Louis receiver Durron Neal , who ranks as the nation’s No. 9 receiver and No. 62 on the ESPNU 150. That was a big pickup, but Missouri landed a blow in the next showdown on Tuesday, when Evan Boehm visited Missouri and gave the Tigers his commitment. “Im a freakin MIZZOU TIGER #NationalChamps,” he tweeted on Tuesday. Boehm is the nation’s No. 1 offensive guard, and ranks No. 55 on the ESPNU 150. A Lee’s Summit, Mo., (Kansas City suburb) native, Boehm comes in at 6-foot-3 and 290 pounds. “They showed me the love that not many showed,” Boehm told ESPN.com. “That’s what really got to me. It wasn’t only the football players and the football coaches there, but it was everyone there. I’m very blessed to have this opportunity.” Here’s the book on Boehm from our scouts: Boehm is a tough linemen displaying the explosion and playing strength necessary to be effective as both a run and pass blocker. Although he is productive at tackle we feel his size and athleticism are better suited for the offensive guard position at the major level of competition. It appears his frame could handle additional body mass over time. Has taken some snaps at center demonstrating the ability to get the ball up quickly, roll his hips with good contact when blocking a “0″ technique defender. Displays very good flexibility, balance and agility, showing the ability to play in space; from both a two and three point stance this prospect demonstrates the initial quickness and explosion necessary to get movement when drive blocking; comes off the ball low and hard with good fit and pad level. Has the flexibility to roll his hips and knock defenders back on their heels; does a good job sustaining blocks due to his balanced blocking base and persistent leg drive. Boehm’s commitment gives Missouri its 10th commitment of the 2012 class, and its first member of the ESPNU 150. But even after Neal and Boehm, the recruiting battles between Oklahoma and Missouri are far from finished. The two schools will clash two more times on two of the top prospects in the 2012 class. Receiver Dorial Green-Beckham , a Springfield, Mo., native, is the top 2012 receiver and the No. 3 prospect on the ESPNU 150. So far, his only two campus visits? Oklahoma and Missouri. The 6-foot-6, 220-pound playmaker has the potential to be a game-changer, and it could come down to the Tigers and Sooners when Green-Beckham is ready to commit. Additionally, the nation’s No. 1 quarterback still counts Oklahoma and Missouri among the finalists for his services. Gunner Kiel , a 6-foot-4, 220-pound passer from Columbus, Ind., has kept his recruitment quiet and very private, but don’t be surprised if either school eventually lands him.
