LeBron James didn't make a decision at midnight on July 1, but he may have taken a meeting. James was seen flying into Los Angeles on June 30. The assumption is that he was flying in to take his free agency meetings. 

There has been rampant discussion all season about LeBron's next destination, but a few favorites have emerged: The gambling odds list the CavaliersLakersRockets, 76ers, SpursWarriorsClippers and Heat as the leading candidates, even though James himself has given no indication one way or another.  

If there's one thing we've learned about James over the course of his career, it's that he's a winner. He's taken teams that had no business being in the Finals all the way to the cusp of a championship, and it's largely because of the fact that he makes his teammates better on a nightly basis with the way he plays the game.

We thought it would be fun to see which team has the most to gain (or in the Cavs' case, the most to lose) if LeBron decides to jump ship once again. SportsLine data scientist Stephen Oh ran scenarios using the 2017-18 schedule to see just how many wins LeBron would be worth. The results, as you might expect, are pretty staggering. Let's start with what would happen if the Cavs lose The King for a second time.

Cleveland Cavaliers

Oh: "Without LeBron, the Cavs drop to 13th in the East and zero percent chance of winning it all. But even if he returned, they only have a 1.8 percent chance of winning the championship."

So the conclusion is that LeBron is really, really good. According to the simulations, any team he joins will have a significantly higher regular season win total, and most will have a legitimate shot at winning the NBA title. And if he joins the Warriors, well, get used to championship parades in the Bay Area.
