As a collective, Celticsblog has been pretty spot on with these predictions.
The biggest surprise in the East is probably how poor the Bucks are...and quite a few CBers noted how poor they'd be with MCW at point over Brandon Knight.
I think some of the teams eventually cool off, such as the Hornets and Pacers have been recently.
I also don't think Detroit or Orlando are teams that will keep up with their records either. However, I still think it's going to be a dogfight among us, Chicago, Indy, Orlando, Detroit, and Washington for the last four spots behind Cleveland, Toronto, Miami, and Atlanta, though I still think Miami and Atlanta are closer to our tier than they are to Cleveland's tier. I think Charlotte and Milwaukee will both be outside of the playoffs as fringe contenders most of the season.
This year's Eastern Conference playoffs should be fun, because outside of the 1-8 series, they all have serious upset potential. There won't be much separating the 2 seed from the 8 seed this year.
I see the playoffs as something like this (barring any major injuries or trades):
1. Cleveland
2. Toronto
3. Atlanta
4. Indy
5. Miami (Health will be the biggest factor with them.)
6. Boston
7. Chicago (I see them fumbling their way through the season with a new coach/system.)
8. Detroit/Washington/Orlando (I know it's a cop-out, but it's still early.)
An Atlanta/Boston series would be really fun, and I bet it at least goes 6 or 7. We matchup pretty well with them, and as long as we're close to fully healthy (especially Smart), I say it's a 50/50 toss-up.
