The Wizards are pretty much running the exact same team out there, while it's pretty safe to say we improved.
They were neverreally competitive in Boston, and I think we are capable of winning there.
Sure 6 games sounds like a safe bet, but I could easily see us getting them out in 5.
Cleveland is still obviously good. Toronto is a good team as well. Neither improved though.
Miami could get better, but they won't make noise. Chicago and Atlanta were tough outs for us last year, but they will be trash. Indy was pretty bad and can now be added to the trash bin too.
So really, the only EC teams that should be noticeably better are the Bucks, the Heat, the Sixers, maybe the Pistons, and the Celtics.
