First is David Lee. Check out the 1 minute mark. To have your PF and C be able to go the distance? Whoa!
Chris Bosh, including the infamous "I wanna be the guy" quote. (obviously from the beginning of last year)
Here is LeBron James, nothing more to be said, I suppose.
Getting "just" James or Bosh is a clear win in my book, especially with three other All-Star level players* already on the team. Getting James and Lee is an underrated coup. Getting both and James, in my opinion, probably creates the greatest collection of young talent in the history of the NBA. (I'm fine if I'm wrong with that.) A good coach makes it the best team ever over the next five years.
Getting anything less than at least Bosh or James is a big disappointment, in my mind. Not a pure failure if they're smart about it, but certainly not a homerun either.
