This was a tough loss, but there were some encouraging signs. Banks had by far his best game of the season, and Jones contributed well on both ends of the court. If not for some bad bounces and inept free-throw shooting, the Suns would have won, on a day where a lot of things weren't in their favor. D'Antoni did a good job with his substitutions in the second half and found ways to keep the Suns in the game.
According to the box score, the Suns had 24 defensive rebounds and the Jazz had 16 offensive rebounds. That means that the Suns collected only 60% of the possible rebounds on their own defensive end. That's completely unacceptable and is the main reason for the loss.
The other problem is that Diaw is mentally soft. His games with four or more turnovers are far too common, given that he really doesn't handle the ball that much. If you foul him and he misses both free throws, which is a distinct possibility, that has the same effect as a turnover. So the bottom line is that he really isn't an efficient offensive option, in spite of his creativity around the basket and occasional pretty pass.
I can't remember who it was who said he hoped Marion would get snubbed for the All-Star team, so that he'd be more motivated the rest of the year -- but he was right.
Anyway, almost a great win.
