Stop guessing there is no logic to your reasoning...
The reason why he left the first time was because the Cavs was stuck in a hole.. Usually when a team gets a superstar they suck for four years allowing them to get other top draft picks, case point Durant sucking allowed them to get Westbrook, Harden, ect... Curry sucking allowed them to get their squad..
With LeBron they litrally went from rags to riches over night not allowing them to get any draft picks and talent.. On top of that no one wanted to sign with them worse yet the little talent they had they had to over pay to keep or let bounce..
By time he left they was over the cap with a team filled with scrubs and no draft picks anywhere in site..
So LeBron got slick and beat the system at its own system.. Thats why he really bolted to Miami, not because he was a sore loser or because he was a flake...
Well now that they have a system in Cleveland where people actually want to play here, and have young talent, this logic does not make sense him bouncing again...
But of course if you fail to follow this logic you will be stuck as guessing and listening to fools who don't know better..
BTW the only way he would bounce is if the team owner gets complacent with one championship and starts refusing to make needed changes that will keep the team competitive, this is the real reason why he signs those one year deals....
