There were reports of LeBron playing through a serious foot injury both prior to and during the playoffs. They are now saying that it was a torn tendon he had in his foot.
talk of walking away from game makes more sense with torn tendon requiring surgery. Thst is a tough rehab for a young guy, let alone the oldest guy in the league.
He may take half the season off to recover and then see how the Lakers are doing.
Also, a lot of talk on the national shows about the Lakers and Warriors making a trade with Lebron going to San Fran and Poole, Kuminga, and 1 other player going to LA (I've seen Wiggins, Moody,, etc.). If it was Wiggins, I could see that for both teams. LA could then move Davis for a prime asset or two (maybe Portland involving 3, Sharpe, etc.) and really rebuild.
