I actually agree with this. While Leonard seemed like a top 2-3 player for awhile, he just isn't consistent enough to compare to those guys. He isn't a good passer at all, or a playmaker who makes those around him better. He was a defensive beast 2014-2016 but who knows if he still has that quickness. His 3-pt shot looked liked it peaked and then got worse.
He's looking more and more like Derrick Rose to me. He looked like a top 2-3 player for a couple years.
Another issue with labeling Leonard a top 5 player is his complete lack of leadership and personality. All of those other guys, with the exception of Anthony Davis, are alpha players that want to be a leader. I don't think Leonard can handle the pressure of being the face of a franchise.
Then there's the fact that he quite possibly has a career ending injury.
