But OU is hoping this is the start of a fantastic 24 hours and not the lone highlight. The good news actually started Monday night when Oakley (Calif.) Freedom five-star running back Joe Mixon reaffirmed his pledge to OU.
Mixon made a visit to UCLA over the weekend, but after a number of discussions, was still all about the Sooners on Monday night and back to being OU's biggest and loudest recruiter.
All that was left to do was make it official. OU was the first offer and ends up being the one that mattered most. Parker said Tuesday A&M and Oklahoma State were both, at one time, very close to getting his commitment.
The Sooners, however, never threw in the towel. OU coaches Bob and Mike Stoops were relentless in trying to land Parker, and it paid off. Parker even gave credit to Mixon for how badly he had been pushing for Parker to be at OU in the last month.
Based off Parker's commitment, OU leapt from No. 21 on Tuesday morning to No. 14 in the Scout rankings. That's how fast things can change.
So what was Parker's message to OU fans? Time to get more recruits in the crimson and cream. And there are three that absolutely stand out heading into signing day and one OU is hoping to lock down from looking elsewhere.
West Valley City (Utah) Granger offensive tackle Kenyon Frison
OU could get some great news early in the morning as Frison is expected to announce between OU, Arizona State, Utah and Nebraska at 8:30 a.m. CST Wednesday. Mixon has been leading the charge hard for Frison to join the Sooners and was back at it Monday night. OU put on a fullcourt press with its coaching staff in hopes to lure the four-star prospect to Norman. Nobody is quite sure where he's going to go, but there's no reason to think OU is out of it. And with the Sooners needing a true offensive tackle, he is a major target.
New Orleans St. Augustine defensive tackle Courtney Garnett
Garnett committed to OU last Thursday following an in-home visit from Bob Stoops. But a supposedly meaningless trip to Notre Dame over the weekend has made things incredibly interesting. Garnett is scheduled to announce around 11 a.m. CST. Garnett's parents didn't make the trip with him to South Bend, but he loves the opportunities that could be there because of Notre Dame's business school. Numerous conversations have occurred with Garnett and coaches at ND and OU in the last 48 hours. He has even considered just waiting until after signing day. Unless something changes Tuesday night, OU will have to sweat this one out.
Oklahoma City Douglass defensive end Deondre Clark
An LSU commit since June, Clark is all set to announce between the Tigers, OU, Arizona State and Ole Miss at 2 p.m. CST. It feels like it's a pure OU vs. LSU battle although that doesn't mean the Rebels or Sun Devils didn't give it their best shot. Clark's mother has made it clear she wishes her son would stay closer to home, but Clark himself has been nothing but positive regarding LSU. The Sooners pursued Clark hard all fall and into the winter after being non-existent in the spring and summer. OU's late push might be enough.
Fresno (Calif.) Central wide receiver Michiah Quick
Quick is ready to make it official sometime after 5 p.m. CST. Because OU's signing day press conference is at 2:30 p.m., there will be no mention of Quick because coaches cannot comment on a recruit who hasn't signed. And if Quick has signed by that time, they're not about to ruin his moment. Like Garnett, this feels like another OU vs. Notre Dame showdown. The Sooners have felt like the team to beat since the summer, but the Irish closed hard in the last couple of weeks. OU made the offer in April 2012, still waiting to see if it pays off.
