Steve Nash (hamstring) says he's "very optimistic" about playing in Game 1 of the Lakers' first-round series on Sunday. Nash practiced fully on Friday after receiving epidural shots to help alleviate the pain. Assuming the shots carry over through the weekend, he could be able to at least suit up, if there's no setbacks. The problem will come when he tries to run and sprint during a game and it remains to be seen how limited Nash and his minutes will be. How Nash's body responds at practice Saturday will go a long way to determining our faith in him.
