The Knicks have Allan Houston as an assistant general manager, Larry Johnson as a player development rep, Herb Williams as an assistant coach. And now Marcus Camby. As a player. The Knicks seem to be reuniting that 1999 NBA Finals team one way or another. "I saw that, especially with Allan the other day down in Houston. Just seeing him brought back so many memories. That shot he hit against Miami and all the great years and experiences we shared and I heard L.J. is back," the 6-foot-11 Camby said at his introductory press conference yesterday. "It's good Mr. Dolan is bringing back former players to be a part of the organization."
