Sometimes it's very revealing to look at the plus-minus stats in the boxscore. This stat shows the point differential while a player was on the court.
From last night's slim victory over the Clippers:
Donte Greene: -13
Omri Casspi: +17
That's a huge disparity.
Greene was recently handed the starting job but there's no real reason why the job shouldn't belong to Casspi. Although a bit selfish, Casspi works harder, shoots better, and brings an attitude.
Here's one vote for a modification to the starting five.
