But after the way the three-star prospect talked about the Sooners last week, it was easily the biggest non-surprise in a while when he committed Monday night.
Curtis is a wide load, for sure, at 6-foot-2 and 340 pounds. His senior season was an up and down outing with many concerned about his work ethic and conditioning.
If that's a problem, he won't last at OU. However, Curtis also sounds determined to prove his critics wrong and said the relationships he has built with OU coaches Bill Bedenbaugh and Tim Kish played a huge role in his commitment.
After committing to Washington in the fall, he said a lot of schools backed off. He was impressed and a little flattered the Sooners kept making the charge. A fantastic official visit to Norman two months ago set the stage for OU winning him over in the end.
Curtis was all about OU all the time last week and it became just a matter of when he would go public with his decision.
He gives the Sooners three interior linemen for the class and is the first true offensive guard in the group. Both Alex Dalton and Jonathan Alvarez can play some at center, while Curtis is squarely set on just being a guard.
OU didn't connect with some mid-year junior college interior guys so the Sooners seem like they're looking toward the future. The 2015 crop of guards and centers is looking great for OU already so perhaps Curtis is more of a project than anything else.
If Curtis does turn into the player the Sooners believe he can be, the reward is certainly worth the risk.
