National signing day will provide its usual flurry of last-minute surprises and drama as most top players will make their commitments and finally agree to scholarship offers from their respective schools.
But today's events will provide special interest for Big 12 schools for a variety of reasons.
Here are some of the late trends to watch from around the conference:
Will Baylor coach Art Briles find some receiving talent to surround scintillating sophomore quarterback Robert Griffin in what appears to be the Bears' top recruiting class of the Big 12 era?
Can Colorado coach Dan Hawkins continue his recent upturn with a late victory in the heated recruiting battle for Byron Moore?
What will the return of Paul Rhoads as the Iowa State's new coach mean for the Cyclones -- and will his familiarity throughout the state result in a fast finish after his late start after his hiring?
Will Mark Mangino have his typical understated recruiting success that has resulted in the Jayhawks' recent North Division ascension?
Will the return of Bill Snyder at Kansas State enable the Wildcats to land a huge statement-making recruit like Bryce Brown or Denard Robinson?
Can Missouri hold onto the commitment of heralded defensive tackle Sheldon Richardson as the foundation for the development of a defense that matches the Tigers' recent offensive success?
Will Nebraska's late surge last season, capped by the Cornhuskers' Gator Bowl victory, result in a couple of late surprises in Bo Pelini's largely settled recruiting class?
Can Oklahoma pluck a late commitment from wide receiver Rueben Randle, the top remaining national commitment, at the Sooners' biggest position of need?
Will Oklahoma State's recent development be marked with similar success recruiting Oklahoma players as it initially appears?
Can Mack Brown pluck a couple of late recruits from heralded signees like Dre Kirkpatrick and Jarvis Jones that would enable the Longhorns to challenge for the No. 1 recruiting class in the nation?
Will the arrival of key recruits like Christine Michael help Mike Sherman cobble together what should be the best recruiting class at Texas A&M in several seasons?
Is the offer of playing Michael Crabtree's old position enough of a lure to attract top recruit Emory Blake to Texas Tech and finish Mike Leach's recruiting class with a flourish?
All of those questions and more will be revealed in the few hours.
