"Having LeBryan Nash a part of the class with him was attractive," Trigonis told Scout.com. "J.P. Olukemi is a sophomore. He had a good year and is returning."
"He wanted to be in a situation where he didn't feel like he had to carry the load," Trigonis added. "Not that he can't do that, but he understands at a higher level he can't do everything by himself."
A number of other high major programs made a play for Guerrero, but the recent coaching changes helped him come up with a decision.
"With [Jeff] Capel going down [at Oklahoma], it made the decision a little easier," Trigonis said. "Iowa was in there too."
Guerrero, a three-star prospect that ranks among the top 25 point guards in the country, also felt comfortable with Travis Ford as his head coach.
"He felt good with Travis being a guard coach," Trigonis said.
Guerrero and Nash, a top 10 recruit, make up their two-man 2011 recruiting class.
