Stephon Marbury officially added Miami to the list of serious suitors during an interview on ESPN’s SportsCenter yesterday.

“I’ve spoken to Boston, to Miami, Mark Cuban (Dallas owner),” Marbury said. “All those talks I’m having is irrelevant because I can’t get out of my deal.”

Marbury created a furor when he told The Post Sunday the Celtics have given him a verbal commitment if he becomes a free agent while blasting Knicks brass for not agreeing to a buyout because it doesn’t want him in Boston.

Marbury told a confidant yesterday he is concerned the league does not want it public teams have given him commitments while under contract with the Knicks, even though Donnie Walsh gave him permission to talk to other teams.

When asked yesterday if he has a commitment from Boston, Marbury tap danced with ESPN.

“If something was to happen, I would be able to pick either of those teams,” Marbury said, referring to Boston and Miami.
