Isiah Thomas is committed to revamping the Knicks' roster by the Feb. 23 trading deadline and is considering making a bid for Denver power forward Kenyon Martin.

According to a league source, the Nuggets are shopping Martin, who will earn $65 million through the 2010 season. Denver has also contacted Chicago about Martin, whose contract and medical history will prevent more teams from pursuing him. Martin, acquired in a sign-and-trade from the Nets two summers ago, has been slowed by knee and back problems this season. Thomas has two weeks to trade Penny Hardaway's expiring contract and has been in conversations with the Nuggets about point guard Earl Watson. According to published reports, the Knicks, Nuggets and Magic are discussing a deal that would bring Watson to New York and send Jamal Crawford to Orlando.

If the Knicks try to acquire both Martin and Watson, Denver may ask for rookie Channing Frye in return. Up to this point, Thomas has sent word that he does not want to trade any of his three rookies.
