What would you rate my fantasy team?

That's a pretty solid team. There are a couple underrated players, but you do have a few overrated players you might consider swapping. Arenas in particular is a bang or bust player, and the last few seasons, he's been a bust. He's hurt more than he plays. David Lee might be doomed to obscurity in Golden State. You might look for another viable scorer because Billups and Brooks don't put up big numbers every night, so someone to supplement those two and make up for what you might not get out of Arenas.
