Diocese of Brooklyn basketball legend Chris Mullin has been named the 20th head coach of the St. John’s University, Jamaica, men’s basketball team, replacing Steve Lavin.

Though he’s never coached, Mullin brings an impressive hoops pedigree, which all started at St. Thomas Aquinas in Flatlands.

He went on the star at Xaverian H.S., Bay Ridge, before becoming the all-time leading scorer at St. John’s and spending 16 years in the NBA.

“It’s great to be home,” Mullin said as he was introduced April 1. “It’s a surreal moment, it really is. St. John’s University has meant so much to me and my family and when that opportunity was presented to me, I couldn’t turn it down. I feel obligated to give back and I’m going to be the best basketball coach I can be.”
