No, you moron. He was the team's best player and only elite perimeter threat. And the team was far from dominant, too dependent on Leonard to create offense and play elite defense.
Now, he's on a team that better blends with him on defense, so he can "take plays off" and allows him to shot to his heart's content.
We'll see if that leads to success in April, May and June (I doubt it, TBH).
And he isn't a leader in any sense of the word. A leader doesn't lie to his teammates about coming back and then change his (last minute), a leader roots on his teammates behind the bench and most of all a leader doesn't sabotage an entire season just to satisfy their selfish needs.
He has led a lot of you gullible idiots to sniff his balls, wipes ass and defend him at every waking second, though. So, yeah, he's a "leader" in that sense.
