The Knicks can still make this a Black Friday for the Celtics with a win tonight. The Knicks try to win their first-round Eastern Conference series in six games, try to get their dynamic duo of Carmelo Anthony and J.R. Smith safely into the second round and ease the panic foaming across Manhattan. And it’s not going to be easy. The Celtics have risen from the dead. After dropping two straight games to Boston, pilloried for their funeral-black wardrobe stunt that backfired in Game 5 Wednesday, the Knicks enter the lion’s den of TD Garden for Game 6 under fire. If they lose again, Game 7 is Sunday at the Garden with a chance at everlasting ignominy as, with a loss in that one, they’d become the first NBA team to fold after leading a series 3-0. The Celtics, meanwhile, are looking to become just like the 2004 Red Sox, who rallied from 3-0 down to beat the Yankees in seven games. “People are going to panic,’’ Iman Shumpert said. “Media, fans, everybody’s going to panic and stuff like that. We can’t do that. We’ve just got to play basketball.’’ Just days ago, the Knicks were the toasts of the town. Now they are slowly becoming a league punch line. Mike Woodson reprimanded them yesterday for wearing all black to symbolize the Celtics’ funeral. Boston reserve Jordan Crawford got in the last word on Anthony following the Game 5 buzzer, with an alleged vulgar crack about his wife, La La Vasquez.
