(Photo by Christian Petersen/Getty Images)Lincoln Riley’s ascent in the college football coaching ranks has been pretty incredible.Bob Stoops ensured that he would get the head coaching job with his unconventional retirement timeline ahead of last season. Riley’s certainly made the most of it.The Sooners have won the Big 12 in both of the young head coach’s seasons atop the programs, and have two berths in the College Football Playoff.Each of Riley’s quarterbacks—Baker Mayfield and Kyler Murray—have taken home the Heisman Trophy as well.Riley has already received a number of contract extensions during his short tenure as head coach.It sounds like another could be coming.Oklahoma athletic director Joe Castiglione just sent a cryptic tweet that many are interpreting as a signal that Lincoln Riley has been given another big contract extension.The use of the eyes emoji is similar to what many coaches send out when they land commitments that they can’t disclose.?— Joe Castiglione (@soonerad) January 1, 2019Riley has drawn significant interest from the NFL, and with 10 openings at that level, it would be a great spot to make that jump if he wants it.He’s maintained that he doesn’t have interest in leaving college right now, though. A big new deal could help seal the deal as well.SiriusXM’s Alex Marvez reported as much on Monday.Don’t expect Lincoln Riley in the NFL anytime soon. I’m told he’s expected to sign a contract extension with @OU_Football sooner than later, which will make my guy @JRsBBQ very happy #BoomerSooner— Alex Marvez (@alexmarvez) December 31, 2018Whenever that is officially announced, assuming it is the case, it will be cause for celebration for the Sooners fans who hope they have yet another long-term head coach in Norman for decades to come.Update: And here it is. From Oklahoma:The University of Oklahoma and head football coach Lincoln Riley have reached an agreement in principle on a contract extension and salary increase. The contract terms are being finalized and will be subject to approval by the OU Board of Regents, which will meet later this month.OU President James Gallogly said the change was made now with the desire to have Riley at the school for many years.“We felt it important to extend and amend Lincoln’s contract at this time as we want him at the University of Oklahoma for a long time,” said Gallogly. “He is a great coach and role model for our student-athletes. His record of success speaks for itself.“Lincoln is also the right representative for our university in such a high-profile position. I am proud to work with him and anxious to support him as he takes our program into the future.”We’ll have more once contract details are released.
