"Yes, he'll be returning to Oklahoma State. There's never been any question about that. He's been a Cowboy all along," Pierce said.
Robinson was a second team All-Mississippi Association off Community and Junior College South Division performer last season as a freshman when he started all nine regular season games and one playoff game for the Bobcats.
He recorded 50 tackles (30 unassisted) with 11 quarterback sacks while forcing two fumbles and recovering one during his freshman season.
"He's just a good athlete," Pierce said. "I'll tell you about him ... last Tuesday we timed our kids and at almost 6-4 and 265 pounds he ran a 4.6 (seconds) in the forty.
"I think he's going to be a great football player. He started from day one here, from the first day he set foot on campus. He's a lot like (Jeremiah) Price, who played here before going to Oklahoma State. He may be a little taller (than Price) but he runs just as well," Pierce continued.
Pierce credits Robinson with turning the Bobcats season around last fall after they began with two losses.
"We were ahead 28-24 in our first home game (against Copiah-Lincoln) but they were driving and going to score if we didn't do something. Ryan fought off his block and ran down the quarterback, stripped him off the ball and we recovered for the win. They were on the 30 with under a minute to play and we didn't have any reason to believe we were going to stop them from scoring," Pierce said.
"I think that one play turned our entire season around because then we won six in a row," the Jones County head coach added.
Pierce says the Cowboys are not only getting a good football player but also an outstanding young man.
"He's just a great kid. He's one of the finest young men we've ever had come through this program," Pierce said. "I think (his impact at Oklahoma State) begins with his character. He'll have a good impact on that program.
"Ryan is the type of guy who shakes your hand and says, 'Yes, sir' and 'No, sir,' like he's supposed to. You'll never have any trouble out of him and you'll never even know he's there unless you speak to him first," added Pierce, who says that Robinson will graduate from Jones County in December and enroll at Oklahoma State for the spring semester and participate in spring practice next year.
Robinson originally signed with Oklahoma State after an outstanding senior season at Mill Creek High School, where he had 85 total tackles (57 unassisted), 14 tackles for loss, 5 sacks and 1 fumble caused.
