For me it's Carmelo. I think it would work and Melo would be that guy, or the primary guy to close out games.
No Dwight Howard for a sidekick though. Who beside's a center would you take to be the one two punch with Lebron.
Rose, Paul, Deron Willians, Kobe, Pierce, Wade, Melo, Bosh, Amare, Durant, Joe Smooth,
Who would be the best fit to play with Bron and why?
