From Howl City:

Williams was benched to start the second half in favor of Dante Cunningham as the trials of D-Won't continued against the Mavs. After a great spin and dunk on Brandon Wright, he followed it up by attempting to lead a fast break, resulting in the usual sequence of a turnover, bad shot, etc. It has been the same old story, and Adelman has been quick to pull the reigns. Against a stretch-4 like Mullens, Williams will face a different kind of challenge than the usual banging down low against the likes of David West or Carlos Boozer. If he fails to extend his defense out to the 3-point line or box out on long rebounds, Cunningham looms.
