It's cute how people still mention LeBron in these discussions like it's 2011. That being said I'd still take Kawhi over Draymond defensively.
I'd definitely rather have Draymond between he and Klay. Draymond does just about everything above average-excellent, whereas Klay has 1 phenomenal skill, one very good skill, and is below average at everything else. I don't think Draymond would be as good on most other teams, but I don't think Klay could be the #1 option on a team either, he lacks the ball handling and ability to penetrate/get to the line that a real legit #1 needs.
