The offer from the Cowboys caught Henderson by surprise considering the Big 12 program didn't show interest until late in spring ball.
"It was surprising, I didn't even know they were going to offer me," Henderson said of receiving the Oklahoma State offer. "I was really happy when they did, I've been wanting for one of the Oklahoma teams to offer me. I thought it was going to be Oklahoma University but it happened to be them. They said if I do come and play for them I'm going to be a defensive end no matter what."
Now that summer is here, like other recruits across the state Henderson is ready to hit the camp circuit. He and several of his Summit teammates plan to his a few camps in the coming weeks.
"I'm trying real hard to go to some good ones," he said. "The first one I'm going to try to go to is in Lancaster, its Texas Tech's. It's either this weekend or next weekend."
Another camp Henderson plans to attend is TCU, but mainly to revisit with the Horned Frog coaches. He hopes to arrange something as soon as this week once he's able to reach his recruiter, Rusty Burns, on the phone.
"I lost his (Burns) because my phone wasn't working but it's working now so I'm going to call him this week so I can call about the camp," he said. "He wants me to come down there and meet up with the coaches again; I was looking forward to doing that with my dad."
Henderson nearly pulled the trigger on a commitment shortly after receiving his offer from TCU. However, after stepping back and evaluating his options more thoroughly, he's pushed back a decision. He does plan to have one made before his senior season gets under way.
"I can guarantee you before school starts that I'll have my mind made up," he said. "It's hard because more schools are coming in and they tell you about their school. TCU is #1 on my list right now."
