With Dallas one of three teams in a tie for sixth place in the Western Conference, every game, especially those against sub-.500 teams, has become crucial at this point in the season.
However, the Warriors have already beaten Dallas this year, a 111-87 pasting on March 10, which was the third night of a back-to-back-to-back.
The Mavericks, meanwhile, will try to continue their strong offensive play from Tuesday, when a balanced scoring attack led them by the Sacramento Kings 110-100.
Without Lamar Odom, Dallas will have a tough time matching up with David Lee, as the 6'9 240 power forward, who had 25 points and 9 rebounds in their last meeting, is too fast for Dirk Nowitzki and Brendan Haywood and too strong for Brandan Wright and Shawn Marion.
The 9:30 PM game will be televised nationally on TNT.
