If they were behind they would. Not sure if they want the clock stopped even if it is Haywood. Don't want a chance for a quick rebound/tip-in. Waste as much clock as possible.

Seems like a bad idea to me. Chandler can replace him and not miss a beat.

More importantly, the Mavs are awesome at free throws. Trailblazers might get Mavs into bonus. Then you have Dirk, Peja, and Kidd on the floor and Haywood on the bench. Those guys make 85%.

You might benefit in first few minutes of quarter. But you'd get hammered in last half.
