Cavs/Pacers/Raptors/Wiz/Bulls/Nets/Bobcats are all easy favorites for the 1-7 seeds.
It wouldnt surprise me though to see Miami intentionally tank, and by intentional I mean sending their healthy starting 5 home half way through the season. Shawn Marion even called Riley out on it when he played for them 5 or 6 years ago ( the year they got the #2 pick)
