Again, like where? I already explained why Cleveland was the perfect situation both basketball-wise and for PR. Plus they had young trade pieces on rookie contracts so they could perform the salary cap gymnastics needed to set up a big 3.
Teams will be willing to move assets if they really want LeBron, or any superstar for that matter. It's a no biggie in the NBA. If it needs to move future first round picks and trade budding superstars to free up cap space for a certified and still in prime superstar, front offices would be willing to do that.
If you want some scenarios, here are some:
Miami Heat - they already have the big 3. They just can be cheap sometimes. Ask Dwyane Wade.
Chicago Bulls - Rose still had it as we've seen this season. They showed interest in getting Carmelo and has pieces to free up cap space, so why not LeBron?
Knicks - they have Carmelo over there. His current teammates in Cleveland came there. James Dolan gives away cash like crazy. It's easy to form another "big 3" there. And there's also Phil Jackson.
Houston Rockets - Darel Morey would be willing to shake up the roster if a scenario of Harden, LeBron and Howard playing together can be realized. Or they can simply let go of Howard and just get a promising talent from the draft.
And there could be more potential scenarios that could've happened last summer. Again, we're talking about superstar free agents here, not just any other players that teams can wonder if they can use their MLEs or could just skip out for the next offseason. Anything is possible.
For example? He needs a superstar young point guard, a vaccuum at 2/3 and room under the cap for an all-star big. Also, needs to stay in the Eastern conference to make sure he has a high percent chance of making the Finals.
Not a lot of choices there.
When did he need a superstar point guard when he plays point guard himself? Unless you consider Mario Chalmers a "superstar point guard."
