No they aren't. A rebuild doesn't involve adding highly paid veterans and random crappy role players. A rebuild would involve trading Bogut, Jennings, and anyone else possible, stockpiling lottery picks, and adding young players. All the Bucks have been doing recently is overpaying unworthy, old players, and then turning around and trading them for more of the same when those players don't work out. They also continuously seem to aim for a low seed in the playoffs, and end up drafting in the middle of the first round almost every year. None of that signals anything resembling a rebuild.
