"It was just time for me to decide. I was really glad to get it out of the way, that was the main thing, making my decision early. I've been liking UCLA for a long time, so when they gave me an offer, I knew the time was right," said McGee.
McGee said he phoned running backs coach Eric Bieniemy last week to deliver the news.
"I talked to Coach Bieniemy and he was really excited then I talked to Coach (Karl) Dorrell and he was really happy too. I talked with Coach (Tom) Cable too. I'm really comfortable with the staff at UCLA and that was a big reason why I chose them," said McGee.
"LSU said they were going to offer once the season starts, but I'm 100% committed to UCLA. Even with LSU being the home school, UCLA is the best fit for me. My family is really excited for me to go to UCLA and my coach said I'm the first player of his to go D-I. Not a whole lot of guys from our school go to big schools, except for (NFL defensive back) Patrick Surtain," said McGee.
The Bruin staff offered McGee as an athlete, and McGee will play mainly running back this year, with some reps at receiver and also will play cornerback.
"I'd really like to play running back, that's my favorite spot. But I'll play any position to help the team," said McGee.
McGee said the commitment came just in time for Edna Karr to start camp, which they do this week.
"Now it's time to focus on my senior year and helping my team win," said McGee.
McGee attended the Scout.com Combine in New Orleans. At that combine, he clocked a 4.54 forty and a 4.2 on the shuttle with a 29-inch vertical.
During his junior year, McGee missed four games because of a freak shoulder injury but rushed for around 800 yards and had 400 yards receiving with eight touchdowns.
He will take his official visit to UCLA the weekend of September 16-18, when the Bruins host Oklahoma at the Rose Bowl.
Academically, McGee has a 3.0 GPA and will take the SAT and ACT in the fall.
