"It was a bummer, but its crazy how things can change and now I have that same excitement when I committed to Cal with Oregon," the Portland (Ore.) Sunset standout said.
The 6-foot-1, 175-pound combo guard said his decision ultimately came down to the new staff at California, Washington State and Oregon.
"Basically I'm really excited to be apart of that program and that class they got coming in is pretty special," Sim said. "I like that style of play and there are a lot of things happening there and I think it was a good opportunity."
The talented guard averaged 22.9 points and 8.8 assists last year for Sunset. He's rated as a three-star prospect on Scout.com.
