He was sitting alongside Cowboy commitments cornerback Jaylon Lane (6-1 1/2, 180) of Nacogdoches, Texas, cornerback ZaCarrius Green (5-11, 190) of Duncanville, Texas; and quarterback John Kolar (6-4, 190) of Norman (North), Oklahoma.
Other recruits confirmed in AT&T Stadium Saturday night included Mesquite (Poteet), Texas linebacker DeAndre McNeal (6-2, 210), and Oklahoma City (Casady School) brothers offensive guard Josh Wariboko (6-3, 305) and defensive back Max Wariboko (5-10, 170). Max is a 2016 prospect as is Edmond (Santa Fe) quarterback Keaton Torre (6-3, 195).
Sunderland, who has been rumored to be leaning toward OU and Ohio State, said he liked what he saw of Oklahoma State.
"Yes sir, OSU, they are young but they did pretty good playing the number-one team in the nation," Sunderland explained. "We were in the lowest level seats, row two I think.
"We were right there and I was watching what they do on defense with their defensive backs and their formations. I was watching Florida State too because their head coach (Jimbo Fisher) called me the other day. He said they would be watching tape on me and that they might offer me."
Sunderland said he had a good time and that they got back home around 2 a.m. He and his teammates at Midwest City open their season on Friday night with Tulsa Booker T. Washington.
"Yeah, we're going to be ready for BTW," he said. "We've been watching tape during lunch and have been getting ready for them for a long time."
Oklahoma State fans would have to think that Texas standout cornerback Jaylon Lane and Za'Carrius Green would have been working on Sunderland to be a teammate of theirs as both Lane and Green are Cowboy pledges.
"I think it went pretty well because they were not giving Oklahoma State a lot of credit because they are so young, but other than a few mistakes and Oklahoma State probably would have won," Lane said. "They only lost to the defending national champions by six points and I think they were averaging beating teams by 42 points last season. That shows how much talent they have."
Lane and his teammates opened their season at Nacogdoches on Friday night with a 27-25 upset of eighth-ranked Kilgore.
"Friday went great because we beat the number eight team," he added. "We got after it. I still made a few plays even though no balls were thrown my way."
This week Nacogdoches will travel to Hallsville, Texas for game two.
Oklahoma State currently stands at 10 commitments in its 2015 class, which is expected to have around 20 members it.
