Mullin led the Red Storm to a (21-13) record this season.
This was the first coaching job by Mullin and it may likely be his last unless he and a smaller mid-major agree to some type of mutual benefit.
Mullin took over for the Red Storm in 2015, and it was clear that he showed improvement every season in the Big East.
"St. John's basketball progressed well during his tenure, culminating with a trip to the NCAA Tournament this past season".
The Red Storm made it to the NCAA Division I First Four in Dayton, Ohio, before being eliminated Hurley's Sun Devils.
When former St. John's star Chris Mullin was named head coach of the men's basketball team four years ago, the university envisioned its most popular player of all-time rescuing a floundering program. Cragg noted Mullin's "contributions" and "deep passion for this program". "We wish him and his family nothing but the best as he begins this new chapter of his life".
"I've been amazed by our coaches, trainers, managers and staff who work relentless hours, which enables this team to grow and thrive". Hurley played at Duke at the same time St. John's Athletic Director Mike Cragg was an athletic department official at the school. NCAA Tournament Selection Sunday will be a lifetime memory.
Fourteen coaches to watch for St. John's: Steve Wojciechowski, Johnny Dawkins, Jon Scheyer, Chris Collins, Tommy Amaker, Jeff Capel, Dan Hurley, Tim Cluess, Steve Forbes, Earl Grant, Mike Rhoades, Travis Ford, Porter Moser and Nathan Davis.
"I think the AD is a Duke man and Bobby Hurley was a great Duke player, and I think he would be an excellent choice", Pitino said.
Meanwhile, St. John's redshirt junior Justin Simon plans to enter the National Basketball Association draft and sign with an agent, sources told ESPN. Transfers Eli Wright (Mississippi State), David Caraher (Houston Baptist) and Ian Steere (NC State) sat out this past season.
