Mavs muscle watch: C/PF Dwight Powell tips the scales at a "fighting weight" of 245 now. He was a bit under 230 at the end of the season, bulked up to as high as 255 and slimmed down to a weight that allows him to maintain his energy and mobility with significantly more strength. (Powell, who signed a four-year, $37 million contract this summer, confirmed that he doesn't carry his wallet onto the scale.) "It's useful weight," coach Rick Carlisle said. "It's not just weight to be heavier. It's muscle, it's basketball weight. It's combination of strength and a little bit more dynamic thrust. It's going to help him."
