The Knicks may not be able to acquire Tracy McGrady from the Rockets due to a reported trade scenario that involves neither team.

The Mavericks and Wizards are believed to be close to a swap that would involve Josh Howard and Caron Butler.

Butler was supposed to be a vital piece in a three-team deal between New York, Houston and Washington that was rumored earlier this week.

A source told The New York Post on Thursday a deal with the Knicks, Wizards and Rockets might be tough to do because all teams couldn't "hit their goals."
