Missing from that list is UCLA, which has been one of Richardson's favorites.
"Since UCLA is so close, I'll frequently visit unofficially, but I'm going to take my official visits to places outside of California."
In fact, Richardson said he may be attending the Bruins' practice this weekend, if not early next week.
Richardson's three scheduled visits will all take place during the season, so he'll be able to get the game-day experience at the three Pac-10 schools he's visiting.
"I'll be at Oregon State for Cincinnati on September 19th, Washington for the Arizona game on October 10th and then Arizona State for the Arizona game on November 28th," said Richardson. "I'm not sure about Utah though."
Richardson said he's still completely wide open, with no favorite having emerged, but his top schools include UCLA, Utah, Arizona State, Washington and Oregon State.
He's also hoping for more offers.
"I really don't have a clue who else might be offering after the season, but I would love to get an offer from an SEC school like Tennessee," said Richardson.
With time on his side, Richardson said he's just enjoying going through the process. "I've still got a whole year left (on the field), so I'll have some more options I think," said Richardson. "I'm going to take my five visits."
Richardson camped at UCLA and USC this past summer as well as Washington, Arizona State, the B2G Camp, the Nike Camp and the Scout.com Combine, where his exceptional athleticism garnered him scholarship offers.
He and his Los Alamitos teammates will begin fall practice next Thursday.
Academically, he has a 2.8 GPA and achieved a qualifying score on the 2-part SAT.
