"That was my first time going to a lot of camps and the first time with the USA," Thomas said. "[The summer] was big for me because it was my first time coming out and the first time people were able to see who I am. This year was big for me."
Now with the high school season under way he's continuing to build his profile.
A standout at Memphis (Tenn.) Melrose, Thomas has led the Golden Wildcats to a 15-0 record and is averaging 18 points and 11 rebounds on a team that includes a handful of other Division-I prospects.
"I've been doing a good job of manning the post this season," Thomas said. "We have a lot of individual guards and weapons on the wings, so I had to play some inside game because I'm tall. So that's my position this year and I'm doing good at that.
"There are a lot of skilled guys on our team," Thomas added. "We have a lot of young guys on our team and just two seniors. There are a lot of guys that play AAU during the summer time and they know how to compete. We have a lot of skilled players."
Thomas, a 6-foot-7, 200-pound wing, may be playing slightly out of position, but that doesn't affect his game. He's the type of prospect that can get things done in the post or on the perimeter.
"I'm a versatile forward/guard that can handle the ball and start the break," Thomas said when describing his game. "I can break down defenders. I'm just a real versatile player that can knock it down from mid-range."
And Thomas' versatility is exactly why he already holds scholarships from Memphis, Tennessee, Missouri, Mississippi, Oklahoma, Oklahoma State, Arizona State, Florida, Memphis, Florida State and Miami.
"I'm still in contact with a lot of coaches," Thomas said. "I'm getting a lot of calls and a couple of coaches have come out to see me."
Thomas doesn't claim any favorites and is still open to new schools. Texas, for example, just joined his recruitment, while a number of other schools have been in to see him.
"Recently I got a call from Texas," he said. "They were talking about they were just now getting a chance and they had a scholarship and they didn't know if I was still open enough to be in contact with them. So Texas is new.
Thomas didn't take any fall visits, and doesn't have anything set up for the near future.
"I think it's still early for me," the five-star prospect said. "I really want to wait until after the summer and see how it goes. Then I'll start breaking it down."
