At one point in November, it appeared that the Bruins were no longer in the mix for the four-star safety, but of late, UCLA has made a surge in his recruitment.
"I'm looking at them quite a bit more and I have a lot of interest in UCLA,' said Riley. "Coach (Rick) Neuheisel is calling me every week and showing a good impression on me and my mom and is making my interest in them a lot more. I'm going to take an official visit there on January 15th."
With more interest coming his way, Riley said his recruitment could go into February.
"I probably won't decide until Signing Day at the earliest but maybe even after Signing Day. I might try and take two more weeks after Signing Day to decide.
Riley has already had in-home visits scheduled with Cal and Tennessee and more will be taken this month and next.
"The in-homes will be good because I can get a glimpse into the programs like I have on the official visits. I'm going to take all five of my official visits too."
The two-way athlete said no one is in the lead for his signature.
"I'm wide open right now," said Riley. "I'm going to take as much time as I need to make my decision, so if that's after Signing Day, I'll take it. With basketball, we sometimes have three games a week, so I'm trying to schedule my official visits around basketball so that could take me past Signing Day."
Most schools are recruiting him as a safety, but Riley said UCLA, Arizona State and Arizona all like him as an athlete, with the opportunity to play on offense there.
One of the few recruits in the class of 2010 who've been heavily recruited since their sophomore years, when he was offered by USC and UCLA, Riley said the long process has been somewhat of a drain, but he's still enjoying it.
"Me and my mom don't ever really talk about recruiting when we talk," said Riley. "I'm still enjoying it somewhat, but it's been a long process. I'm a pretty cool and chill guy, but a lot of fans are taking it really serious. They're always leaving me messages on Facebook and Twitter. But I've been really fortunate to go through this for the last two years. It's been an awesome experience. So I try to look at it like that."
Riley was selected to the UnderArmour All-America Game, an opportunity he is looking forward to.
"I'm on the team with Jesse Scroggins, Josh Shaw and George Uko and I'm rooming with George," said Riley. "It will be a fun experience to play with a lot of these guys from around the country that I've met at a lot of camps and combines. Me and Josh Shaw are going to hold it down in the secondary for the White Team. We get to play against the top players and we hope to compete with the best of them."
Riley said he will be doing regular graduation at St. Francis, enrolling for summer school wherever he signs.
In the meantime, he's balancing his recruitment with a return to the basketball court.
"I'll play my first game this week against Maranatha," said Riley. "I took some time to rest my hamstring after the playoffs ended so I come back this week."
Riley finished his senior year with 899 yards on 125 carries and nine touchdowns, had 29 receptions for 436 yards and five touchdowns and had 64 tackles, six breakups and three picks on defense. He was a four-time all-Mission League pick.
