Anderson, from Jersey City (New Jersey) St. Anthony's, chose the Bruins over hometown Seton Hall, St. John's, Florida and Georgetown.
"The biggest thing that stood out is the tradition of UCLA," Anderson said, "And its track record for putting guards in the NBA."
Anderson had taken a number of unofficial visits, and one official visit to Florida last weekend.
But when asked if the visits played a major part in his decision, Anderson said: "The visits were not that important. I enjoyed the visits (three of them) but it didn't play a major part."
What was the hardest part of the decision?
"The process was very hard as far as making the choice because I want to play for all five of the coaches," Anderson said. "So I guess the decision was real hard."
Fitting in at UCLA also played a big part in his decision.
"I think I fit in well (at UCLA). We will have three or four upperclass bigs that will probably be pros and right now we have Jordan Adams and Dominic Artis (also committed from the class of 2012). Both can score and Dom is a very good point, too. When I get on the floor I will have a lot of weapons to make passes to."
Not only is the commitment of Anderson to UCLA significant in itself, but Anderson is also close friends with the #1 player in the nation, Shabazz Muhammad, and Anderson's commitment is considered to be an indication that Muhammad will join his friend in Westwood.
