He's the cherry on top but the overall roster is still better and you don't make it that far without the roster.
They still have another tier 1 superstar. They have two old vet former stars who ate really good role players. Rondo is Playoff Rondo. Guys like KCP and Green. Kuzma averaged 19 and 5 in his 2nd year. Morris and McGee.

Nobody is saying lebron isn't lebron. He gets his teams there for sure. But he advances and wins titles because of their whole rosters.
