Except that Curry has the numbers to back it up.
Flavor of the month is very common, and it's very true that some people are quick to promote the latest as the greatest. But it's also true that Curry is objectively performing at a level (at least in terms of shooting) that is absolutely unprecedented in NBA history. No one else is even remotely close. Some people, trying to fight against flavor of the month, refuse to acknowledge that reality.
Ray Allen and Reggie Miller are 1-2 for most 3 point FG's made in a career (with Miller 466 ahead of the 3rd place guy, Jason Terry). Most people would concede that they were the 2 best high volume 3 point shooters in NBA history. The most 3 pointers that Allen ever made in a season was 269, the most that Miller made was 229 (when the line was shorter). Steph Curry is on pace to hit 418.
The NBA record for career 3 pt % is held by Steve Kerr, at .454. Curry is shooting better than that this year, while averaging 11 attempts per game. Curry's % would be among the top 50 single season marks ever, and he's doing that while on pace to break the record for attempts by 232.
Curry is redefining what's possible when it comes to perimeter shooting. If not, if Curry is just an outlier and no one else comes along anytime soon who's at least near him, then what does that say about Curry?
