Ex-Knicks stud Chris Childs is going off on James Dolan ... telling TMZ Sports the New York owner mishandled the Spike Lee situation and is turning the team into a JOKE!!!
"This has to stop because it's starting to be the laughingstock of the league," Childs says. "And, I hate to see that."
If you missed it, Lee and the Knicks spent all of Tuesday fighting over the entrance the movie mogul used at Monday night's game. In fact, the beef got so bad, Spike vowed to not return to MSG again this season.
