I actually came over the computer to say the same thing.
Westbrook really cost them the game with his poor shot selection, poor ball handling, and that huge defensive lapse on the final play of the game.
I thought Kevin Martin looked great in that 6th man role though. I can't wait to see how good he can be when he's actually had some time to gel with the rest of the team. Yeah, he's the third option now, but that could be a good thing for a guy who's had to be the one carrying the team offensively for pretty much his entire career.
One thing that I noticed though was how Russell Westbrook felt uncomfortable passing to him. There were several plays where Martin had created some space for himself, asked for the ball, and Westbrook would look right at him and take it to the goal himself or pass it elsewhere. I'm not sure what to make of that: Shitty decision making by Westbrook because he's just a shitty decision maker,... or shitty decision making by Westbrook because he doesn't trust Martin yet.
