Smith, the veteran head man, made a huge impact on Onwuasor.
"I loved coach Tubby Smith," he said. "He's a great coach and a great person. People say he's hard to play for, but he's going to expect a lot out of me."
On the court, Onwuasor hopes to provide a spark as a freshman in Lubbock.
"I want to do whatever the coach asks," he said. "Just come in and work hard to compete for a spot. Bringing a positive attitude and energy is important."
In addition to Smith, another individual on the TTU campus created a very solid impression with Onwuasor.
"I met with Chancellor Hance," he said. "At most schools, you meet with academic advisors and student supporters, but I got to meet the head of the university. That showed me that they really wanted me."
Although Lubbock is over 1,100 miles away from Inglewood, Onwuasor isn't worried about the distance.
"You have to make an adjustment to any school so I would have had to deal with anyways," he said. "Texas Tech was the best place for me, so the distance wasn't a factor at all."
On the court, Onwuasor felt the open style of play and getting up and down was suitable for his game.
"That's where I can help out a team," he said. "I can play in transition and find open teammates as well as creating for myself."
After the Red Raiders had made their pitch though, a final gesture made a lasting exclamation on his visit to the Lone Star state.
"My flight was at 5 a.m. and Coach Smith woke up and took me to the airport," he said. "I don't think any head coach would've done that. That meant a lot to me and I'm excited to get there."
