Chris Mullin intends to re-sign Monta Ellis but the Cavs and Heat are pursuing potential sign-and-trades to acquire Ellis.  

Alan Hahn of Newsday also cites a person close to Ellis saying that  the budding star "would be very interested in the Knicks" and especially playing for Mike D'Antoni.

The Knicks are monitoring the situation but won't make a formal move unless Mullin signals that he's ready to talk about parting with Ellis.  Donnie Walsh and Mullin have a close personal relationship.
