On the flip side, arguably the 3 best PGs of all time (Magic, Stockton, Kidd) were/are not great 3 pt shooters.

I’d also guess that having a PG who’s in love with the 3 is a huge detriment to any team’s offensive flow. Baron Davis comes to mind.

What your continued research should eventually unearth is that 3FG% at the PG position is a critical factor in a team’s ability to win basketball games. It’s not the amount of points that are scored by the PG on 3PT shots that matters most but the fact that a team’s PG is perceived by his coach and teammates, and the opposition’s coach and players, to be someone who has the ability to knock down open 3PT shots at a high [adequate] percentage when presented with those opportunities.

Good coaches the world over have been aware of this very fact for a long time.

e.g. The fewer 3’s taken by a PG the better, as long as that PG is capable of making the ones he does take at a solid percentage, when it comes to winning/losing basketball games and most importantly league championships.

Nice data but I don’t feel like we gain much from it. It makes sense that a good three point shooter regardless of position would increase his team’s offense efficiency. Still, it’s interesting but I think the relationship between these data is merely correlation at best.

I would guess that better shooters would positively affect offensive efficiency across the board. Are you planning to extend the study to see if this is true and, if so, whether the point guards demonstrate the greatest influence?
