The freshman from Inglewood (Calif.) High School has the size and speed to make an immediate impact, and with help from the team's best players, he's working on putting it all together in time for the 2011 season.
"Camp and practices have been going pretty good, I have a lot to learn," Onwuasor said. "I'm young, so I have a lot to learn still. I've been looking up to Juron (Criner) and he's been teaching me a lot right now.
"Right now Juron is like my big brother. Every little thing he sees he's always telling me and I'm always trying to fix it. He stays back with me after practice to try to fix stuff and little stuff like that. It means a lot to me. That's what we talked about when I first came; he told me that he'd be a big brother to me."
Under Criner's watchful eye, the 6-foot-1, 190-pound receiver is working on fine-tuning all of the little things that go into being a successful college receiver.
"I'm working right now on my footwork and coming back to the ball and getting back down hill, stuff like that," Onwuasor said. "My feet have really improved, I'm moving my feet better and picking up my feet more."
With a less talented group of receivers, it's likely Onwuasor would have a good chance at making an impact on the offense as a true freshman. While he may be behind some of the other receivers in the group, Onwuasor will likely work in on special teams to help him adjust to the college game until he cracks the rotation at receiver.
"I think I have a chance to contribute this year," Onwuasor said. "They want me to play a lot of special teams, so I'll probably do that. I bring a lot to the table, I just have to get used to the system and then I can really get going.
"Right now the game is just a lot faster, so I have to pick up the speed and keep working hard. I think that I'm making that adjustment well though so far."
The quicker he's able to pick up Arizona's offense and adjust to the speed of Pac-12 football, the quicker Onwuasor will be able to accomplish the goals that he's set for himself for his freshman year.
"I just want to get on the field and do what I have to do and listen to my coaches," Onwuasor said. "I just want to do what I have to get on to the field."
As a former resident of Los Angeles, it's no surprise that aside from the team's normal goals for the 2011 season, that Onwuasor has one game in particular circled on his calendar.
"Team goals, we want to get to a bowl game," Onwuasor said. "We want to win all of our close games. And we want to beat USC."
