Why does it feel like the team has officially passed the torch to Luka on his arrival but it never felt this way with AD?

Luka has officially been handed the torch or given the keys to the team. Everyone expects him to be the star that will bring multiple championships and LeBron can finally step back

Before the trade, it never felt this way with AD. It always felt like AD was still LeBron’s robin.

Does anyone else get this vibe?
