The 6-foot-3, 240-pound Lewis, who committed to the Bruins as a running back, said he is trying to enroll in January.
"I want to, but I have to make sure everything is in order," he said during the Pylon 7v7 at Bruin Stadium. "I'm focused on my schoolwork and getting a ring and winning a state championship."
Lewis competes in 7-on-7 events as a receiver, but he admitted playing there in college would take a lot of work.
"If I was a receiver in college, it would have taken me one or two years to get acclimated to playing it," Lewis said. "My natural position is running back, so as soon as I get there, I'll be ready to play."
The way UCLA used Myles Jack was a big reason Lewis chose the Bruins. Jack, who also plays linebacker, rushed for 267 yards on 38 carries, and scored seven touchdowns as a running back. He also was fifth on the team with 75 tackles.
Meanwhile, Lewis ran for 515 yards and eight touchdowns, and had 33 catches for 498 yards and six touchdowns as a junior.
"It shows even at his size, he can be explosive in that offense," Lewis said. "That proves when I get there I can do the same thing, if not better. He's a real good guy."
Although Lewis is on the other side of the country he still has schools looking to recruit him – Florida, LSU and Arizona State are still talking to him. He said, though, "I'm really solid," and UCLA's staff is working hard to remain engaged with him.
"Coach (Jim) Mora and I talk a few times a week," Lewis said. (Offensive coordinator Noel) Mazzone and I, we talk every now and again. Every day I'm talking to different coach."
And it was the coaching staff, particularly on the offensive side of the ball, that led Lewis to UCLA.
"Coach Mora is a real good guy," Lewis said. "They're building a lot at UCLA, and him being a new (college) coach, he has a lot of energy and he is fired up. The running backs coach, Kennedy Polamalu, he has a lot of status, so that was a plus as well.
"The campus had a great atmosphere. All your classes are right beside each other, so you don't really have to walk that far to get to your next class, so that is good. I got to see all the academic stuff. Everything is right there for you."
