Steph Currys normalized it though.
It's not that Curry started logo threes and pull up 3s. Its that he normalized that shyt to where it is common at all stages of the game, and for even role players to do it
LeBron did deep threees, but mostly when the the shot clock or quarter clock was winding down.
Kobe and TMac did pull up threes, but mostly on a heat check.
Currys legacy is in how you see A LOT of players do it CASUALLY - not just when they have the hot hand or late in games. Curry made this shyt a normal part of an offense.
Pull up threes, logo threes, off the dribble iso threes, off balance fade away threes, etc. Used to be situational/circumstantial, but now it's in afterthought. Role players are expected to do them now.
Lebron's main flaws offensively are that his handles/crossover abilities are not great, and that his post game is still limited moves wise. He still gets it in at a good clip, but the lack of a sheer bag prevents him from doing it consistently.
I feel like as he has put on size, he has lost his mobility and nimbleness.
