From ESPN'S Chat with David Thorpe:
Rory(Sacramento): How much do you think Kevin Martin's ankle is effecting him, both on offense and defense? I've gotta hope that he at some point becomes at least an average defender.
SportsNation David Thorpe: It's really bad after a game. When he gets rest, like after the all-star break or their recent 5 day break, he's been fantastic on both ends.
