Lincoln Riley is in the middle of a transition period from Oklahoma to Southern Cal, and that comes with assistants moving between programs and trying to continue recruiting.

That transition may have caught assistant coach Roy Manning in between schools, and on the wrong side of NCAA rules.

A paper trail on social media shows that Manning, who coached cornerbacks under Riley at Oklahoma, appears to have made recruiting efforts for both schools, John E. Hoover of SI Sooners reported. The OU Compliance Twitter account even tweeted about it with a couple of emojis. That came after multiple recruits noted that Manning made recruiting visits or communication with them.

As Hoover reported, USC recruit Domani Jackson told 247 Sports’ Greg Biggins that Riley was “blowing up my phone” and said Riley “wants to send in coach (Alex) Grinch and then he’ll come in later. I’ve heard from coach Grinch too and also Roy Manning, who was the DB coach at OU. I’ve been texting back and forth with coach Manning, and looking forward to meeting those guys in person.”

According to Jackson, Manning is recruiting him as a representative of USC. Jackson told 247 Sports that he’s now cut his list of schools down to Alabama and USC.
