These are stats from his tenure in Opava 2001-2003, Czech NBL league, where he played total of 90 games in a span of 3 years, while already being 36 years old, with 2.5/6.4 per game total, on a 40% 3pt shooting.
Guy was the youngest pro at the time (in freakin 80s) that played first pro game at age of 14, for Borac Cacak, in a Yugoslavia that at the time was 2nd to NBA in quality (time of Partizan, jugoplastika)
I will try to find FMP stats but let's just presume that those were different times, and playing in your 36y is not as it is today and you may be in a serious decline ... ?
Shooting at the basket that is down relative to you is inexplicably hard.
We had some weird gym that had improvised stands right next to a court, so the distance was like a 28ish ft 3pt shot. And the height was so that you are just slightly above the rim from your shooting position
Your mindset is for the ball to go up and then down. But in this instance, yu basically need to just shoot it downwards. and it messes up your complete sense of shooting, it's like 3/4 are airballs.
