2013 postseason alone he defended Monta Ellis (2), Mike Dunleavy (3), Jimmy Butler (3), Carlos Boozer (4), Paul George (3), David West (4), Kawhi Leonard (3), and Tony Parker (1). I wanna say he defended Lance (2) and Manu (2) as well but I can't remember for sure. And of course he would have guarded Rose (1) again if he had been healthy.
Hell, this article from the first round said that Bron was shutting down literally everyone.
LeBron James may soon receive his fourth Most Valuable Player award, largely for his offensive prowess, but his defensive skills may be unmatched.

I agree with your other point though - even though I think Bron would be ahead of Kobe anyway (due to similar perimeter defense with more versatility and better defensive leadership), the biggest difference in their impact is that Bron's rim protection affects the other team's entire squad. Kobe on defense never changed the whole floor like that.
2016, you could see by Game 7 that Golden State was shook as fukk to drive to the rim to the point they weren't even trying anymore and when they did get there they usually missed (8-20 shooting at the rim for the game). That was cause of LBJ. Lebron's 16 blocks in the series were the most of ANY player in a Finals between 2011 and 2021 - no one else had more than 12.
Steph's body language after every Bron block was straight defeated.
