Golden State GM Chris Mullin is expected to emerge as a top candidate for the Knicks' GM job if Isiah Thomas eventually is fired from his dual role as coach and president, The Post has learned.

Mullin was at sold-out Madison Square Garden on Tuesday and heard all the "Fire Isiah" chants as his Warriors belted the Knicks by 26 points.

The former St. John's sharp-shooting superstar out of Brooklyn told a confidant Wednesday that an employee from the organization, during an informal chat, secretly asked Mullin if he'd be interested in coming to the Knicks if the GM spot is open next summer.

Owner James Dolan is not ready to make a move yet, and Thomas will coach the team tomorrow against the Bulls, though he appears on thin ice.

Mullin, 43, is in his fourth season as Golden State's executive VP of basketball operations and has built a young, athletic team that posted one of the biggest playoff upsets in NBA history when it shocked the Mavericks in the first round of the playoffs last spring.
