Here are some Steph Curry stats I found. He's currently taking 12.1 3's per 36 minutes (!) and shooting 45% (!!!)
In the history of the league (well, since the 3 point line, I guess), there have been 14 seasons when a player averaged 10 3 pointers attempted per 36. The top of the list, by %, is
1) Steph Curry 45.4%
2) Steph Curry 45.0%
3) Steph Curry 41.1%
Troy Daniels, believe it or not, in limited minutes last year, took 10.2 3's per 36 and shot right at 40%. It's just crazy how far ahead of the pack Steph is when you consider the sheer number of 3's he takes.
Put another way, there have been 69 seasons in NBA history where a guy who shot 45% or better from 3 (50 made 3s minimum). When you sort them by 3's made per 36, you get
1) Steph 12.1
2) Steph 11.8
3) Kyle Korver 7.4
He is lapping the field!! No one else has come close to the volume and % from 3.
