Stan Van Gundy is getting a ton of support from his Orlando Magic family after the loss of his beloved wife ... with a ton of former players and staffers coming together to visit the coach -- including Dwight Howard, Vince Carter and Patrick Ewing.
Several stars smiled as they posed with coach ... with the big man explaining the meeting was all about SVG.
"We all came out to support our leader and one of the best coaches in history of the game," Gortat said." Coach Stan Van Gundy. #nba #family #orlando #florida."
Howard -- who played under Van Gundy for five seasons -- penned an emotional Instagram post when Kim passed away ... saying he would always be there for him.
"We've been through it all, and these are the times that we need each other the most. My deepest condolences, thoughts, and prayers go out to you from the bottom of my heart," Howard said.
"I want you to know that myself and everyone from our Orlando team loves you and has your back through this time!"
"Mrs. Kim will forever be missed, but rest easy knowing we got him from here on out."
