Seeing how the Bulls-Heat series has been going I think that the Nets have a really good chance of making it to the Eastern Conference finals. Obviously we have to take care of Indiana first, but now that we got home court advantage back I don't think that's going to be too much of a problem. As for Detroit, I think we can pull that one off as well - 2 of Detroit's 18 losses were to the Nets and the Nets have beaten them in Detroit (yeah, I know, playoffs are a totally different atmosphere, yada yada yada). Don't discount the Nets, they've gone to the NBA finals before when they were being underestimated, and those were teams that weren't as good as the one we have now.
Some people have put the Nets out of it because of what's happening with Indiana but that's just the Nets, they'll lose games to crappy teams and will kill good teams (I was at the game not too long ago when they gave the Suns a thorough thrashing and kept Nash to 0 points).
If nothing else, well, at least we're not the Suns.
