"People ask me why I do it," said Chai, who also coaches girls in the Fountain Valley-based Team Complete Athlete club volleyball program. "But volleyball is a big part of my life and I really enjoy the game. And with John being the head coach, I get to enjoy spending time with a good buddy of mine."
Speraw is among those who marvel at Chai's dedication.
"We don't pay him much, and he drives a lot, but he does it because he loves the game and he's a good friend," Speraw said. "He's gregarious, he has a great perspective, and he's a pleasure to have on the bench."
Chai has earned the respect and friendship of the players, to whom he dispenses near-equal amounts of playing tips, good-natured ribbing and unyielding support.
