There are like 2 people in the 50/50/90 club. Kerr and Nash I believe. 1 season each I think.
I think there are like 8 or so in the 50/40/90 club. I believe Nash is the leading guy there. Probably the best shooter of them all really. Funny he wasn't really known for that but his shooting was unreal.
