One of the notable holes in the Knicks' roster that will persist after the Carmelo Anthony trade is a capable, defensive-minded center. The Knicks tried to fill that hole with efforts to draw Portland into the deal as the fourth team and bring Marcus Camby back to New York, two people with knowledge of the talks told CBSSports.com.

It wasn't clear what pieces the Knicks would've sent to the Trail Blazers in such a scenario, but both sources said Tuesday afternoon that New York's efforts to get Camby failed. The three-team, 13-player Anthony trade went through Tuesday night with only one minor addition -- Kosta Koufos going from Minnesota to Denver for a second-round pick.
