ricky davis is a cancer...
...he has so much appeal, always carries that fair contract, and each coach/gm believes that they have the "right environment" for ricky to finally succeed.
...then after a couple months (if even that long) you've seen enough and want to pawn him off to the next fool.
Here is my only question...what good team with leadership has he ever played on?
He played on a Cavs team where their leader was an 18 year old kid, and was pretty terrible.
He played on a Celtics team that was incredibly mediocre, and who traded away their veteran leadership to get him.
He played on a Minnesota team that was in full tank mode, and were in a general disarray, despite KG's best efforts.
He played on a Miami team that went into full tank mode when they realized their superstar was injured, and the rest of their roster looked like an NBDL all-star team.
Although I agree there may not be much evidence that he is a good character guy, there also is little evidence of him actually being a cancer. He just is a guy who has never been in a good situation. There are a ton of guys in the league with similar personalities, but have been lucky to be in the right place at the right time (see Rasheed Wallace, Josh Howard to name a couple).
