A commitment from San Diego big man Angelo Chol on Thursday further suggests that the Arizona Wildcats' rise on the basketball court will be sustained.

Chol, a 6-foot-8-inch, 210-pound shot-blocking forward, chose Arizona over traditional powerhouses Kansas and North Carolina as well as Pac-10 rival Washington during a news conference at his Hoover High School.

Chol's commitment gives the Wildcats four top-75 players in the class of 2011, with guards Nick Johnson and Josiah Turner, plus offensively gifted forward Sidiki Johnson, already having signed letters of intent in the fall.

"You get two (big) guys in the class that complement each other, and you could also have the best backcourt in the league the next couple of years," ESPN analyst Dave Telep said. "I'm not surprised at all. Sean Miller made his bones as a recruiter, and he's making his mark as a coach. The guy is really good at his job with a huge name to sell."

Hoover coach Ollie Goulston, said Thursday that he and Chol initially rejected Miller's interest in the fall of 2009. But Goulston said Miller kept developing a relationship, was eventually invited to see Chol, and then closed the door.

"Coach Miller persevered and wouldn't take 'no' for an answer," Goulston said.

Having eliminated Washington and Alabama on Tuesday, Chol said he didn't make a final decision until Wednesday night.

"I liked their basketball system," Chol said via telephone after the news conference. "I felt like it was the place to go for me."

Chol is averaging 23.4 points, 14.8 rebounds, and 8.1 blocked shots per game for Hoover this season. Sidiki Johnson is considered a more polished scorer, but Chol is shooting 36 percent from three-point range.

"He's a shot-blocker/rebounder, and he runs the floor well," Rivals analyst Jerry Meyer said. "The reason he isn't ranked a little higher is that, at least on the traveling circuit, he doesn't always bring the energy you have to have to be a high-level defender and shot-blocker."
