NORMAN — The wild, up-and-down nature of Oklahoma's football recruiting isn't likely to ease up anytime soon.
Uncommitted Laquon Treadwell, the top-ranked receiver nationally from Crete, Ill., and Nico Falah, a four-star offensive tackle and current USC commitment, each visited Oklahoma this weekend.
The important visits come after a crazy couple of weeks during which OU convinced a pair of defensive linemen to change commitments, but also lost out on important prospects.
Dallas Kimball defensive tackle Justin Manning — whose brother, DeMarcus Granger, was a Sooner tackle from 2006-09 — picked Texas A&M over Oklahoma on Dec. 6.
Manning told Rivals.com that he always wanted to be a Sooner, but that OU was one of the last schools to offer him a scholarship, and that was what began his shift away from Oklahoma.
But on Dec. 12, Houston three-star defensive end and longtime Oklahoma State commitment Ogbonnia Okoronkwo became the first OSU-to-OU flip since cornerback Demontre Hurst in 2009.
Two days later, four-star Dallas Skyline defensive tackle Kerrick Huggins flipped from Texas A&M to Oklahoma.
The Sooners didn't sign a defensive tackle prospect in last year's class, and Huggins became the first such commitment this year.
As the defensive-tackle situation begins to look better, though, offensive tackle has become a concern for OU, making Falah's visit all the more important.
Oklahoma's only offensive tackle commitment, Tulsa Union's Dalton Rodriguez, decommitted, choosing instead to play defensive end at Tulsa.
Falah (6-foot-4, 267 pounds) is the 16th-rated offensive tackle prospect in the country, according to Rivals.com.
As of now, Treadwell doesn't have any more official visits scheduled; he's narrowed his list of prospective schools to OU, OSU, Ole Miss and Michigan.
