it's likely to be achieve next season, in my estimate, Curry is making an average of 3 to 4 3 point shots per game, that's regardless of the result of the game, so if he will stay healthy and of course consistent then breaking the all time record is not a problem. However, his record is also not hard to break as the game now is more on 3 point shooting, we also have players who are shooting that average on a daily basis and they are still young now.
That's the result or influenced by him itself. After that dominance from the last few seasons Steph and Klay changed the game, now it's more on taking 3's than penetrating, more on offense to be your defense than protecting the basket.
He deserve to be known as the best rainbow arc administer. Bringing this type of game to this league after Reggie Miller's era, surpassing Miller already a success but it would be more delighful if he'll break the top seeder and put his name to this legacy.
I think it is obvious that people are shooting a lot more threes nowadays with a bit of help from Curry. Obviously as the best three point shooter we have ever seen in history of NBA and as soon to be record breakingly high three pointers made in a career, he did affected and impacted the league a lot. However I would like to point out that analytics played a bit of a role as well, not saying that is the only reason obviously but I would say analytics had a good part in changing basketball too.
You look at teams and where they shoot from these days and you can see that (except spurs maybe lol) most teams are either shooting from very close, such as layups or dunks, or they shoot threes, there is very little midrange shooting these days in the NBA. Which is why I think it is a bit about steph and klay winning that many rings shooting threes, but it is a bit about analytics as well.
