NBA: Miami Heat overrated this year?

[llabb]

Yes, they have loads of talent on paper now, but is Miami a lock to make the NBA finals and be the Eastern Conference champs? People are betting like it is.

When WSEX opened the Eastern Conference lines, it set them at:
Miami +150
Detroit +310
Indiana +350
These lines favor Miami, but seem somewhat reasonable.

Now WSEX has opened its futures markets on the subject, and bettors have shifted the odds to:
MIAMI 39 44 +127
INDIANA 14 18 +455
DETROIT 13 17 +488

At these prices, you can get Indiana and Detroit COMBINED for +185 profit if EITHER of them win! That sounds like great odds to me, a gift due to all the hype about Miami. Does this sound good to the rest of you as well?
