I wouldn't say he's a better athlete or knows how to run a team better, he just has better guys around him. He turns the ball over less but he also doesn't have to create as much as Kyrie.
Kyrie is underrated athletically, he's not going to dunk like Dame but speed wise they are even, I've seen Kyrie put the burners on Westbrook and we know his level athletically.
Put kyrie on the blazers with that roster and he puts up better stats than Dame. My own opinion though
