Shoot first PG's rarely win NBA titles. Pass first PG's have won the vast majority of NBA titles throughout NBA history.
This isn't true at all. I posted something on this some time in the last week. Scoring PG's are far more likely to win a championship than Passing PG's. Even if you look at the all time great PG's that were a first or second option on title teams (Magic is the clear exception not the rule). Just look back to the Isiah (scoring) title teams and work forward: Isiah (scoring), Paxson (scoring), Cassell (scoring), Harper (scoring), A. Johnson (passing), Fisher/Harper x5 (scoring), Parker x3 (scoring), Billups (scoring), Payton/Williams (scoring), Rondo (passing), Kidd (passing).
Many of those guys were afterthoughts in their offenses, it doesn't matter if they were passing or scoring point guards. Also, Isiah certainly fits into the passing point guard category, he's top 5 all time in assists/game. The players on your list that were somewhat major parts of their offenses that weren't really great at distributing/running their offense were probably Billups, Parker and Cassell.
Zeke was the leading scorer on the Pistons both years they won the title. That is a scoring PG. Stephon Marbury is 16th in APG, is he a pass-first PG? What about Kevin Johnson (9th)? Tim Hardaway (11th)? Baron Davis (21st)? Tiny Archibald (20th)? And there are plenty of others in the top 30 or so all time.
Of the PG's that were arguably a top 3 player on a championship team all time and even giving you Isiah as a hybrid - you have Kidd (passing), Parker (scoring), Billups (scoring), Zeke (hybrid), Magic (passing), Frazier (scoring), Tiny (scoring), JoJO White (scoring), Goodrich (scoring), Dandridge (scoring), Cousy (hybrid).
The reality is, scoring trumps passing.
