But Roberts is feeling pretty confident that a few more Pac-10 schools could be joining that group.
"My four offers are from Stanford, Washington State, Oregon and Colorado," said Roberts. "Cal, Arizona State, UCLA and Arizona are all planning to come by and I feel pretty good that they could be offering me soon."
Roberts returned from Oregon's Junior Day over the weekend, and he left Eugene pretty impressed with what he saw.
"The weather is a lot different than here, but otherwise, it was great," said Roberts. "The coaches were really cool and seeing the stadium and the facilities was like nothing else. They gave us the whole tour before the Spring Game. It was pretty cool, too, they didn't put any pressure on me to commit. The coaches said they'll let me decide on my own and that the offer is on the table."
Roberts has already been to USC and Stanford for their Junior Days, and he's planning to take unofficial visits to Cal and UCLA sometime in the spring or early summer.
"Coach (Ron) Gould at Cal said that he is going to be coming down pretty soon to my school," said Roberts. "UCLA has been sending me mail daily and they want to come out and see me, too."
Roberts said he's completely wide open, and he's not ready to narrow down the list or name a favorite, let alone make a commitment. "I've heard from a lot of my fellow athletes to take all of your visits and go on an official visit before you decide," said Roberts. "I'm looking at sometime by January, maybe sooner."
Roberts is planning on camping at USC this summer as well as attending the UnderArmour/Scout.com Combine and the PrepStar All-American Camp. In March, he was part of the "CaliTwo" squad that won the Badger/New Level Pass Camp in Las Vegas.
"That was a great experience and I had a lot of fun playing with some great athletes," said Roberts. "It was fun to win it, too."
Roberts said that if he had to pick a region to play his college ball, the West Coast would be his first choice. "I'm pretty sure it's going to be the West Coast," said Roberts. "My family is pretty dedicated to staying in the West."
Roberts had over 1,000 all-purpose yards, with many coming as a kick returner, and scored seven touchdowns.
Academically, he has a 4.1 GPA and scored a 1600 on his first attempt at the SAT. He is enrolled in two AP classes and two honors classes.
