Wilson Chandler already has one foot out the door but it's that other foot that could potentially sabotage a trade for Carmelo Anthony. The Knicks forward continues to experience discomfort in his surgically repaired left ankle and, according to a Knicks source, the fear is that Chandler may need yet another surgical procedure after the season, which would be the third in three years. On June 3, 2008, Chandler had surgery on his left ankle to remove bone spurs and nine months later he had surgery to remove scar tissue. He recently missed three games with a sore left calf, which could be related to his ankle problems. Publicly, Chandler says the ankle is fine but privately he is worried about the long-term ramifications, especially since he will become a restricted free agent on July 1. The news comes at a bad time for the Knicks, who are hoping to include Chandler in a trade to Denver for Anthony. The Knicks would prefer to keep Danilo Gallinari instead of Chandler, mainly because of Chandler's pending free agency but also because of his history of injuries. In the most recent reported trade proposal, Chandler, 23, would be headed to the Nuggets along with Minnesota's Corey Brewer. The Timberwolves would throw in a first-round pick. The Knicks would then send Anthony Randolph and Eddy Curry's expiring contract to Minnesota. It's a lopsided trade in the Knicks' favor, especially when you consider that the Nets were willing to trade Denver three No. 1 picks. The Nuggets have until the Feb. 24 trading deadline to move Anthony, or wait until after their season ends - but before he becomes a free agent on July 1. Anthony has made it clear from the start that he wants to play in New York. Lately, Anthony has given mixed signals about whether he wants out of Denver - or is willing to sign an extension with the Nuggets - but it's clear that Chandler doesn't want in.
