Rockets guard Kevin Martin has been in the NBA long enough — eight seasons — to know slumps come and go. If he needed a reminder, he has seen slumps pass through the locker room this season like a bad cold. That does not make it easier to be the afflicted scorer. It does help, Martin said, that the Rockets have won three of the four games in which he struggled, with the players off the bench — Chase Budinger, Courtney Lee and Goran Dragic — making up for the lack of output from the team's leading scorer. Still, Martin, who averages 18 points per game, and the Rockets would welcome the return of his shooting touch. "I really have no idea, no idea," Martin, 29, said of how a slump caught him. "I just have to keep playing through it. I just have to go with the flow of the game and just go from there."
