Steph is arguably the most influential NBA player we've seen since Jordan. Only other person I could see a case for is AI
Man changed the way the entire league plays
He changed it for the worse. I can't bear to watch every single team chuck low percentage 3 point shots leading to massive blowouts cause they go cold every other game.
But he did change it. Not all influences are good influences unfortunately
This is casual history by fans. Steph is not the reason the league shoots more 3pts.
In 2014 the Rockets led the league with 2179 3pt attempts. Steph and the Warriors were back in 6th place.
In 2015 the Rockets set a new record with 2680 3pt attempts, the first team to shoot 30+ threes a game (nearly 33/game). Warriors were in 4th.
In 2016 the Warriors and Rockets were neck-and-neck, with Warriors edging them out 31.6 threes/game to 30.9.
2017 the Rockets blew the Warriors out of the water with over 40 threes/game, another record. Warriors were way back in 5th again.
2018 the Rockets broke their own record averaging 42 threes/game. Warriors were all the way back in SIXTEENTH place, yet won the title.
2019 the Rockets hit a new level with 45 threes/game. Bucks had 38, Hawks and Mavs 37, Nets 36....Warriors all the way back in 8th place.
Steph was the face for casuals because he's so good. But NBA teams weren't copying Steph, no one could copy Steph because they don't shoot like Steph. And the Warriors don't spam threes like that, they've only been top-3 in 3pt attempts once in Steph's entire tenure. NBA teams shoot more threes due to analytics, and if they're copying anyone they're copying the #1 analytics team - the Houston Rockets. That's why their offenses look like Houston's offense, they don't look like Golden State's offense.
