Sophomore forward Angelo Chol will transfer from the Arizona Wildcats, according to his high school coach and mentor.

Ollie Goulston, who coached the Sudan native at Hoover High School, said this evening that Chol decided to leave in order to find a bigger playing role elsewhere. San Diego State is among his possible destinations.

"It's been a very difficult decision for Angelo -- he's been wrestling with this for a while," Goulston said. "He had a lot of sleepless nights, but at the end of the day he wanted a bigger role in a situation where minutes were available.

"He liked Arizona, being a part of the team, the coaching staff, and coach (Sean) Miller, but he wanted the opportunity to play a greater role. It was a numbers game."

Chol’s playing time shrank from 12.2 to 8.5 minutes last season as a sophomore when UA brought in freshmen big men Grant Jerrett, Brandon Ashley and Kaleb Tarczewski.

While Jerrett decided to turn professional last month, Top 5 forward Aaron Gordon committed to Arizona, leaving Chol in a potentially similar situation. In addition, UA has junior college transfer Matt Korcheck coming off a redshirt year.

Goulston said Jerrett's departure actually may have hurt Chol's chances of staying. With Jerrett returning, Goulston said, Chol was considering a redshirt season in 2013-14 but once Jerrett left and Chol was asked about playing again next season, Chol began wondering if he would be in the same place.

Chol played his best game of last season on Feb. 6 against Stanford when Jerrett was out with a foot injury, collecting six points and eight rebounds in 24 minutes. He also had eight points and four points two games later at Colorado but did not record double-digit minutes the rest of the season.

Chol averaged 1.9 points and 2.0 rebounds as a sophomore while playing in 28 of 35 games. He averaged 2.8 points and 2.3 rebounds a game as a freshman in 2011-12.
