It’s hard to rank all time PG’s. After Magic and Curry(if you consider him a one), everything is subjective.
Centers and PFs are pretty easy to rank the top five of all time. Small forwards and shooting guards can be tough as well. LeBron and Bird are one and two. MJ and Kobe are one and two. 3-5 is a bit tough.

Rank your top 5 PGs since 1980. Let’s call Curry a one for this exercise. We don’t have to throw in Oscar, Cousy and Jerry West. What’s your top five?

If Isiah makes everybody’s top five that leaves two spots. Stockton, Paul, Nash, Kidd, Payton, Westbrook, Harden(is he a one?). Is it too soon for Shai and Luka?
Reddit has Westbrook off the top ten list. His is tough.
