In addition to adding the extra weight before the season, Thomas is looking at other improvements, mostly mentally.
“I'd like to play with a little more swagger this year,” Thomas said. “Knowing that I have to be a leader this year and everything that comes with it, I want to play how I know I can play and be completely confident in myself.”
Thomas also hopes for a healthy season after a couple of setbacks relating to a shoulder injury he suffered as a sophomore.
Against Catoosa that year, he tore the ligament that connects his sternum and clavicle.
He tweaked the injury in the state championship game and then again during the spring.
In late June, he finished physical therapy as he heals from the injury.
“I feel really good now,” Thomas said. “I'm ready to go.”
Arkansas State, Tulsa and Kansas are among the teams who could be close to extending an offer to Thomas.
He's been to camps at all three schools and has another visit scheduled to Iowa State later this month.
