Even if you want to say Magic might not be the flat out best in certain areas, he’s at least in contention. There’s tons of non-3pt shooting scenarios where Steph is clearly not even close to the best, and I think you can make a similar argument that your making against Magic when it comes to catch and shoot 3s. A post hook is a shot, an elbow fade is a shot, tons of ways the best shooter ever isn’t even serviceable, what ways can Magic just not pass the ball? He played PnR in his career.
You’re admitting exactly what I was getting at though, that when we call Steph the greatest shooter of all time it’s really with the qualifier of 3pt shooting than just overall, which isn’t a fair comparison. You can’t take every type of passing into account for Magic and only consider 3pt shooting for Steph.
Also, the PnR was in the game way before the Jazz were formed as a team. They were running PnRs in the 60s.
