I mean just look at the rest of the league. Not many of the good teams have an elite facilitating PG on their team. Players that can put the ball in the basket are the most important in today's game.
Okay...let's look at the rest of the league...
Top 10 Teams in the NBA (by current record):
1. Warriors - Have Curry (11th in the NBA in Assists Per game) and Green (9th in APG; 2nd among non point guards) and their team leads the league in APG.
2. Spurs - Point guard is arguably their biggest weakness this year; team is 6th in league in APG. Give me Pop and the Spurs system, and I will quit asking for anything more.
3. Rockets - Found success by putting Harden as the lead facilitator (leads league with 11.3 APG)
4. Celtics - Team is 4th in league in APG
5. Cavs - PG is not elite distributor, but Lebron runs things and is 6th in the entire league in APG.
6. Wizards - John Wall is 2nd in the league in APG
7. Jazz - Their star center just called out their starting pg for not passing enough.
8. Clippers - Chris Paul (4th in league in APG)
9. Raptors - Kyle Lowry (10th in league in APG)
10. Thunder - Russell Westbrook (3rd in league in APG)
7 of the 10 NBA leaders in PPG are on top 10 teams.
7 of the 10 NBA leaders in APG are on top 10 teams.
Rubio is an outlier because of his horrible shooting. Otherwise, Jrue Holiday is the only pg in the top 10 in assists whose team is not in the playoffs. Incidentally, that same team has 2 elite scorers.
It seems to me that having an elite distributor is pretty much essential unless you are the Spurs. We are not the Spurs. It also helps if they are elite at scoring, but IT, Lillard and Irving are the only PGs who are elite at scoring (25 ppg) and not at distributing.
Lillard's team is not that good, LeBron does the facilitating for the Cavs, and IT pretty clearly has a ceiling, due in large part to his score-first focus. They are all top 25 in the league in APG.
Sure, if you have an elite distributor who can't score it limits you, but the same is true about an elite scorer at the PG spot who doesn't pass.
I certainly don't see the statistics to back up scoring over passing from the PG position. If anything, it seems they are equally important. Elite scorers at other positions (Booker!) are easier to find than elite distributors.
Also, I'm no pro athlete, but I've played enough basketball to know that I much prefer playing with a pg who passes versus one who doesn't. I doubt NBA players view this differently.
