Sam Cassell has joined the Wizards as an assistant coach, and will work with superstar guard Gilbert Arenas.

"He's better," Cassel said of Arenas on ESPN 980 in DC.

"He'll be ready for opening night. He's ready. We rely on Gil to do a lot of things for us - not just scoring, but being a leader. That's why I'm here. I'm here to show him how to be a leader. If you don't know, you don't know. There's nothing wrong with not knowing something. That means you got room to improve and learn."
