It appears James Harden is hurt — he is day-to-day with a bruised foot tweets Jonathan Feigen of the the Houston Chronicle. Those tend not to keep people out long if at all, and against the Lakers he certainly was aggressive and attacking when he had the ball.
Harden’s defense has been pretty bad all season, and it’s something the Rockets have to fix if they are serious about contending. Right now he is just reaching, not moving his feet.
The Rockets play the Clippers Saturday in a rematch of last Monday’s game where Harden was a defensive mess — he was assigned to J.J. Redick early and the Clippers ran Redick off screens like he was vintage Ray Allen.
