Greene, who led the Cavaliers to the CIF State D-II title in December, joined three of his Serra teammates in Westwood.
"It was pretty good up at UCLA and was good seeing the coaching staff again," said Greene. "I know Coach Noel Mazzone and Coach Taylor Mazzone really well. We sat down in the film room with Coach Taylor and we watched some film of Brett Hundley. They talked about what they like from their quarterbacks and what quarterbacks fit their system."
Greene is being recruited as well by Adrian Klemm, who has Serra as one of the schools in his region.
"Coach Klemm and I have a really good relationship, he recruited a lot of guys from here when he was at SMU," said Greene. "He's recruiting me too with Coach Mazzone. UCLA has been recruiting me since the start of my junior year."
"I'd been on campus before for their camps, but we got to take a really good tour before the basketball game," said Greene. "It was really nice. When I was there before, they hadn't built the gym all the way but it was cool going to the game."
While Greene doesn't have any offers yet, a handful of schools are spending a good deal of time recruiting him.
"Miami, Arizona State, Boise State, those three have been recruiting me the hardest with UCLA," said Greene. "I want to camp at Arizona State and Boise State and then I want to take an unofficial to Miami and go to Notre Dame's camp. I don't really have a favorite school. I grew up liking Florida but I'm wide open right now."
Last fall, Greene helped the Cavaliers win their second state championship in four years, throwing for 2,500 yards and 26 touchdowns and rushing for 1,100 yards and nine touchdowns. The Cavs will also welcome back one of the more loaded rosters in California next fall.
"It felt good winning the state championship, when a lot of people doubted us, so it was a big accomplishment to get it done," said Greene. "Now we want to win the Open Division title."
This spring, Greene will play quarterback for the Frat Boyz on the 7on7 circuit.
