Derek Fisher's out ... and now Dennis Rodman wants in!
Kim Jong-un's favorite NBA Hall of Famer has officially thrown his boa into the ring to be the next head coach of the NY Knicks -- and he's even posted a message directed at Phil Jackson.
"Hey @PhilJackson11 @nyknicks, I have a pretty decent resume on the court and I can coach; and I'm available. Call me. @nba."
Fisher was fired earlier Monday and Kurt Rambis was named interim head coach.
Worm wants a shot ... think Phil will give it to him?
