I would love to see KG and Russell go against each other in their primes.
This matchup is interesting because, in fact, both KG & Russell are probably the last guys I think of for 'one-on-one' matchups.
The wonderful, fantastic thing about both KG & Russell is that they are/were ultimate _TEAM_ players.
Yeah, sure, they are amazing individual basketball players, too. But that's not what made each special. Russell & KG are far more special because of how they elevate a team around them.
So it is odd to think of them in any sort of one-on-one matchup.
