To me, it looks like this:
1st tier: Cleveland
2nd tier: Everyone else
I honestly don't see that much of a separation between 2-8, and I even think teams like Indiana and Charlotte in that same conversation, too. I mean, is it really that crazy to see Boston landing a home court advantage in the first round, especially given possible injuries? For example:
Chicago: new coach, questionable chemistry, bad injury history
Atlanta: lost Carroll (which was really big in my opinion), seemed to really overachieve in regular season last year, certainly injury-prone as well
Miami: Injury-prone
Washington: questionable coaching, loss of PP (which was also really big in my opinion)
Toronto: questionable coaching, might have peaked, loss of AJ
Milwaukee: young team that will be very good but I'm not sure they're ready to make the leap just yet, still need to see Kidd coach more than one good year before considering him more than a question mark
There are pretty big question marks for every team ranked ahead of us (as well as our own, i.e. lack of true star talent), but I think Boston and Milwaukee are the most stable teams in that category considering the factors of injuries, chemistry, coaching, depth etc., though their ceilings aren't as high as the other teams. It really wouldn't surprise me to see Boston land anywhere from 4 - 10 right now, and I think they're just about as likely to be 4th as they are 10th, which suggests that predicting a 7th or 8th seed is probably safe.
