Again, I really don't see any intent there. They don't give two shits who they play in the East. Think about it: if you were them, is there a single team you'd fear? Earlier in the season, maybe Indiana. But now? Puuuh-lease! They've pounded much better Bulls teams, and that's the only moderately scary opponent to them in the East.
If they're not scared, why would they tank? They're not, and they didn't.
The Nets, on the other hand... just fucking pathetic. Their tanking is pathetic, and the fact that they're trying to say WE wanted the matchup (because of an innocuous comment from Ross) is even more pathetic. I hope we make them eat their words!
