Thomas committed to Houston at the Cougars' Junior Day event yesterday.
"Coach Middleton was at Evangel last year and I trust him," said Thomas. "He's like a big brother to me. We're really close.
"My mom was really proud of me. She thinks it was a good decision, because I also have family connections in Houston."
What did Thomas think about the campus?
"They have great facilities," he said. "They have, by far, the best facilities I've seen.
"It feels good to commit, so now I can focus on school at Evangel. I think I'll be able to play early at Houston. They offered me a couple of weeks after National Signing Day, and the coaches were a little surprised that I went ahead and committed yesterday. They didn't think it would happen that soon."
Thomas was accompanied to the Junior Day by teammate X'Zavier Preston, a standout inside linebacker.
"He loved it," Thomas said of Preston. "He's just waiting on Houston to offer."
Evangel Christian lost to John Curtis in the 2011 Class 2A state finals, and Thomas is eager to get on the field and try to help the Eagles reclaim the crown.
Evangel won state titles in 2009 and 2010.
"I'm ready for the season to start and see how it goes," said Thomas, who measured 6-foot-6 and 329 pounds at the Junior Day.
"I feel like my strengths are pass protection and run blocking. I just need to improve my footwork and get more aggressive - work on blowing people off the ball."
Thomas reported additional offers from Mississippi State, Vanderbilt and North Texas.
