The closest thing to a real "super team" outside of Miami is the one OKC built through the draft.
All these other combos or organizations are flawed and teams like LA Lakers, Chicago (if Rose ever comes back near 80% even) and San Antonio will be better teams still despite having less splash by not landing any Superfriends mega-squads.
LeBron-Wade-Bosh is such a better 1-3 punch than any of the other combos. And OKC's draft created Durant-Westbrook-Harden-Ibaka is the best 1-4 punch. You could argue Allen makes Miami a Big 4 because he's going to be standing around wide open, he'll be Super Kerr/Armstrong. And at some point OKC will have to pay up for their draft studs but they'll be in a position of power for a while.
Howard is an egomaniac and a potential cancer despite maybe being the second or third most skilled player on the planet. The Knicks are the most poorly ran franchise in sports. I see it as a two team power struggle now with a handful of teams like SA, Lakers, Clippers and Bulls having a chance to move up in the next year or two with a move or player development. I'll be shocked of NYN or Brooklyn rapidly improve into contenders, especially NYN.
