The more I think about it, the more I love the look of a lineup of IT, Brown, Hayward, George, and Horford. I mean, that's pretty much exactly how the Warriors are built. Green is definitely more of a PF than George, but I think PG can play PF full-time in this modern NBA.
I think that'd almost assuredly mean that the Cavs trade Love for Melo, too, because they'd have to try and matchup with us. Their current lineup has no shot at defending us out on the perimeter.
