From an article in 2012:

"Chew also found familiarity when he accepted the position at Marquette because of his long-standing relationship with Williams. They first met while Williams was recruiting point guard Marcus Denmon, who was playing under Chew for Kansas City Pump ‘N Run. Denmon wound up at Missouri with Mike Anderson, where Chew would eventually coach him in 2011. More importantly, Williams and Chew began a friendship that went beyond Division I and AAU coach.

“He was genuine with me as I was with him,” Chew said. “I never had relationship with guys as a Division I coach; I had relationships to be cool with him. I would text him here and there, and when I was on the road he would encourage me throughout the years and we stayed in touch.”
