Makes you wonder if Curry and 3 pointers will be like stolen bases were before and after Ricky. Henderson had a 15 year run where his ability to get on base via hit or walk totally changed the flow of an inning. More teams will try to do what GS is doing, but there's a fine line where diminishing returns become a high risk. There's only a dozen or so players in the world who can shoot as good as Steph. But they don't have his ball handling, conditioning, passing, etc.
Interesting comparison, I think more apt than the NFL passing game, because like RickyH, Curry is a truly unique athletic talent that is extending the limits of what is possible. You can't see Curry's skill in the same obvious stand-out way of Ricky's raw athleticism, but Curry is both unique and breaking a barrier. It is kind of like the 4-minute mile and as Curry proves you can shoot more 3's and shoot them accurately from greater distance others can accept the possibility.
The game is changing because of the confluence of analytics, rules and 3-pointers being around for so long that now kids are practicing shooting from distance very early. Larry Bird never heard of a 3-point shot until he was in the NBA.
Curry has some very unique physical gifts that are hard to quantify, its almost like a Pedro Martinez or Ron Guidry ability to throw 99MPH despite slight of stature - a rare and almost impossible to replicate gift for coordinating movements. And I think Curry and Thompson have a unique mental advantage having grown up playing in NBA arenas as children and are somehow hyper-acclimated to shooting well in those environments.
So though I expect Curry's records to last, I also expect lots of players to surpass the old records and 3-pt shooting quantities, accuracies and distances will continue to increase.
