Again, when i say the Spurs aren't forced to go with him, that obviously applies to both ends of the floor. Matt hustles, has good footwork and plays fundamental D. He struggles when he's forced to guard highly athletic players - Marion with Dallas, Amare with the Suns - and the Spurs couldn't play McDyess 40 min and were many times forced to go with Bonner. This shouldn't be the issue any more. His defense isn't changing, so if he's hitting from the outside he's a great asset. If he's not, the Spurs don't have to give him minutes, especially if he's facing unfavorable defensive matchups.
