Shooting is very easy to quantify and it's still a huge part of basketball, that is one metric that one can use, you have not provided any metrics of your own, so by default I have put forth more actual evidence in this discussion.
You're just appealing to outliers, yeah it's not ALWAYS the case that if you add more people to the talent pool it gets better, but that's not what we see in other sports where the play is through the roof as the talent pool has increased. You're just using technicalities to weasel your way out of the arguments.
Athletecism is a skill and so is effective coaching, you can deny it for whatever reason, but even the most athletic players put immense work into their "athleticism."
The bottom line is this, you have not attempted to put forth any evidence for your position, so there is no way you can win this. You can say my evidence isn't great, but I'm pretty sure everyone agrees that shooting is an important skill and thus my evidence>>>>>>>""""""""""""yours"""""""""""""
