Forward Caron Butler is having a rough year on the struggling Washington Wizards. And forward Josh Howard is having an even rougher year on the very solid Dallas Mavericks. Both players could use a change of scenery, and that’s reportedly going to happen tonight.

UPDATE: The trade is official. Click here.

According to at least four media outlets, including the Washington Post (Michael Lee), the Mavericks will trade Howard, forward/center Drew Gooden, guard Quinton Ross and forward James Singleton to the Wizards for Butler, center Brendan Haywood and guard DeShawn Stevenson.

Howard this season is averaging just 12.5 points, 3.6 rebounds and 1.4 assists on 40.1% shooting in 26.7 minutes per game. His role on the Mavs has been in decline.

Butler averages 16.9 points, 6.7 rebounds, 2.3 assists and 1.45 steals on 42.2% shooting in 39.4 minutes per game.

In the view of InsideHoops.com, this seems like a good deal for both teams. Butler gets to join a winning team he can contribute to, though he’ll be asked to be more of a role player than he may be used to. And Howard gains more responsibility, something that may do him good.

The most important player in this trade other than those two guys is Haywood, a solid center having a good season. He should definitely help Dallas.

More coming tonight when the deal actually becomes official.
