Which of Lebron, Westbrook, Harden, Davis, Curry, Durant, or Paul is he better than?
I can't really see a case for Leonard over any of them, and a case could be made for Antetokounmpo as well.
We can argue his exact placement, but that's really immaterial. Upgrading from Derozan to Leonard isn't a big enough upgrade to change the team's fortunes. The Raptors are still clearly worse than the Sixers and Celtics. I guess this is a big enough upgrade to make sure that they stay ahead of the Pacers though, but somehow I don't think that was the point of the move.
