Lebron will go back to cavs 100% before he stop playing. Cavaliers will be his retiring team. FOr me, If there will be a trade with LBJ, it is good for the cavs as they are really in need a good SF/PF.
King might be old but still playing like a prime of other players. Cavs need to wait for LBJ! dont do trade for now.
I don't think LeBron will end his career with the Cavs. He used to really want to win a title with the Cavs, and he did so in 2016. But now I don't see any particular reason why LeBron would suddenly decide to move to the Cavs, especially if he is determined to win another ring.
The Cavaliers are already a great team now, and he wants to win a ring, his chances in the Cavaliers are still high since they already have Mitchell, Garland, Mobley and Allen as their key players. I mean if I will compare his chances of winning a title if he stays in LA and his chances of winning a title if he's on the Cavaliers, the chances of him winning a title if he's a Cavalier is way higher.
TBH, I don't see any reason as well, but for me, I have this feeling that he might end it on the team where he started it all. I mean who knows.

He might surprise his solid fans as well and goes back to Cleveland and accepts a much lower contract. On the flip side, there's a chance that he might end up in another team that's willing to pay him huge amount of money, but if he prioritizes winning a title rather than the money (assuming that he will play next regular season), it's better for him to go an established team with many all-star players already.
