Why wouldn't they? Are there really eight teams in the east that are clearly better than Milwaukee? Maybe if they were relying on Bogut, but with this trade, they clearly seem ready to make a push right now.
I mean, six are probably a lock (Indiana, Detroit, Miami, New Jersey, Chicago, Philadelphia), but I think that Milwaukee, Cleveland, New York, Washington, Boston and possibly Orlando will be in a dogfight for the last two spots.
