I don't even know if Kobe is in my top 20 all time, I know he isn't that close to my top 10. That just strikes me as a bad pick, I think the only potential saving grace is SG is the weakest position in league history so there is some value in reaching for the 2nd best SG. Again though, I think that is a bad pick.
Kawhi was an absolutely terrible pick. I don't even think I would have selected him before the 4th round (and maybe not even then). Even taking the 1 season approach, I just don't see the logic or value in it. He is at best an average rebounder, he doesn't pass the ball well, he doesn't bring the ball up the court or run an offense. Obviously a great defender and can score well, but there are much better scorers that are just flat out better all around players even looking at it just 1 year at a time. And if you use this year, he missed 22 games, that has to factor into an analysis of who he is as a player. I just absolutely hate that pick.
EDIT: And I'm aware that in this type of draft having a great defender who can score and not do much else may be ok as other players will do that, but it just strikes me as a huge talent downgrade from every one else's 1st pick.
