For the Heat
First of all, the Heat have Riley in charge, so the locker room will not be chaotic.
The Big Three of the Second Heat have a strong emotional foundation. They are all old acquaintances and know each other well.
The Big Three of the Third Heat formed a partnership after the end of their second contract. They got all the honors they could get and earned about the same amount of money.
As for the Cavaliers
First of all, no one is holding the line, and the boss is mostly conniving towards the players.
Secondly, there is no emotional foundation. Everyone has become a monk halfway, and there has been no relevant discussion before.
Third, except for LeBron, everyone else has no honors and doesn't earn much money.
I feel that the biggest failure of the Cavaliers is to find a rookie coach. If this is a new team, it can still give the coach time.
But in the Cavaliers, the coach has no authority for big names like James and Irving. There is no time for bosses.
Behind Spoelstra there is Riley, who can suppress the Heat's Big Three, and if it really doesn't work for the boss, he can still go to the old man.
