@zjcvols Simmons was talking about Shai being one of the best guards ever. I was thinking he is specifically a combo guard, and he may already be the best ever, and well on his way to being the greatest ever. I figure these are the top 11 guys:
Jerry West
DWade
Shai
Iverson
Harden
Dumars
Jrue
Arenas
Hornacek
Spyda
Dame
I'm sure I'm forgetting some guys. "Combo guard" is subjective, but to me it's a guy typically with tweener guard size, who basically runs point but is score first, and can play off-ball.
I do not think Curry qualifies, because I do not think Curry looks to score first. Warriors do a unique thing where he runs point mostly trying to set up his own off-ball action. Westbrook was not an off ball guy at all during his prime, so not included.
Edit: Wiki page about combo guards mentions Booker, Terry, Jamal Murray, and Manu
