Not a juggernaut, but a really tough mismatch. Not only do you have Flagg as a 6'9" do everything player that is hard to guard, but they are humongous all over the court. I think they could be challenged by any of these really fast athletic teams who apply a lot of pressure (Houston, StJ).
I don't think we'd stand a chance personally, as we don't have the kind of personnel to challenge them, we're just a weaker version. Against any of these top teams, our only chance is to catch fire from 3 (the great equalizer).
