What's amazing is how long they stuck in the league when they're losers and they make teams worse. Oh, and how much they get paid for destroying team morale, increasing losses, and getting people fired. Combined, the three have probably made like $200 million.
The only exception was early in AI's career with Philly, when they pandered to him and built a team around him.
Otherwise? He's made every team he's been on substantially worse.
I would take AI out of that list what team did he actually make worse? The Pistons maybe, but he just is not as good as Billups so of course the Pistons would not be as good. Not to mention the Pistons didn't look the same since Ben Wallace left the team. I have never been a fan of Iverson, but do you not remember when he led a horrible 76ers team to the NBA Finals? The other two are horrible cancers though you are correct.
He was not a cancer to them he just was not as good as Billups. The Nuggets got BETTER when he got to the team so that isn't really the definition of cancer. They where much better with Billups who is the better player the same can be said for the Pistons. That doesn't classify as a cancer though.
