"First of all, it's the USA," Colbert said. "That was the first thing that stood out to me. I was surprised that they called me, knowing that I made it to the USA football team, that's [made up of] everybody in the country. Knowing that I have the capability to do something great, in something I love, that really stood out to me."
He said he also recognized the uniqueness of the event.
"It's great," Colbert said. "There's no type of Olympics or anything else in football. So this is our one chance to represent football in the United States."
And that hasn't always been an easy experience this week.
"It was tough at first, because you have to get used to a new system, and you have to learn to work together as a team," Colbert said. "But as we progress, we get a lot better as a team.
"It's a great feeling," Colbert said. "It feels like I haven't had pads on in two years. It feels great to hit people again."
Colbert is hoping that hitting people will lead to more recruiting attention. He said he's talked to a few coaches who are watching him, including those at Texas State, Oklahoma State and Connecticut. All of those coaches said they liked Colbert's motor for his 315-pound size. And while he still has his senior year at Fort Worth Southwest to make an impression, Colbert said making the USA team could prove as his leaping-off point.
"I think it will be a big jump for me," Colbert said. "I don't have any offers, but knowing that I'm on a team full of guys who are committed to big schools, or have plenty of offers, can only help me."
