"Then, yesterday, he made the offer official. He said I would be an early starter at Tech; they need players like me to make a great program there."
With that in mind, what's the current status of Roos' recruitment?
"My top five - and this includes consideration of each school's track program - are Texas, Oklahoma, Kansas, Purdue and Louisiana Tech is up there," he said. "I don't want to single out a particular school, nor do I want to rule out any schools. I'm keeping my options open.
What is important to Roos when it comes to choosing a program?
"I want to play early," he replied. "I've started since my freshman year in Celina. I like playing - being on the field. If I'm going to get the most playing time at a particular school...I would definitely like that and consider it."
Roos' athleticism is off the charts. He benches 435 pounds, boosts 390 on incline and squats 505 pounds. To top it off, he has a vertical of 29 inches (at 6-foot-5, 300 pounds).
Roos consistently throws 60-plus feet in the shot put. He ranked second in the nation this year with a best of 64-1.
This week, he's camping at Oklahoma, followed by stints at Texas and Baylor's respective camps.
Celina, which also features big-time junior lineman Jake Raulerson, went 11-1 last year.
"We'll be really good again," said Roos. "We have a huge offensive line. We open holes as big as Texas for people to run through."
