Can Cleveland win a championship? I doubt it. They'll lose in the playoffs before too long. If he wants to win a championship next season and win another ring, he'll need a better team. He's still very athletic and a true superstar, but he can't win a championship on his own; he needs a few more players.
LeBron and Donovan Mitchell could make a good duo, but I definitely don't think they'll be enough. He could win a ring with a team like GSW, but even that would be tough
Well, I kinda agree with you about GSW, but they would be way above the salary cap. The question is, are they willing to go that far just to get James? but that would be lit. Imagine Curry and James playing together as Warriors and during a farewell tour at that. I can already imagine ticket prices skyrocketing, especially at their home court. But he could also win with the Cavs. Aside from Mitchell, they have Garland, Mobley, and Allen, all three averaging double digits. Plus, they acquired Nance Jr. and Lonzo Ball as well. Just because they choked in the playoffs doesn't mean they're not title contenders.
