You can't simply take their best traits from the past and then give them the best traits of today. It doesn't work that way.
Look, those guys were the best players. But if you want to create a team that would beat anyone, you balance out your skills. And your team doesn't have any 3-PT threats. If you are going to magically give every guy from the past 10% boosts to their 3-point shooting, then this is a pointless discussion. Otherwise, give me Curry and his 44% 3-PT shooting to add to that team.
