You look at things all wrong. Sure they were two games over 500, but where was the Knicks the season before?
If theywere going to finish 500 plus, they'd be around 43-39 or 44-40 for a 14-15 game increase in wins from the previous season. Which is a good first step.
Keep in mind Lebron's cavs team was a much betters defensive team than the Knicks this season and also played a few seasons together. And this is with no trade drama swirling about.
You're still confusing being a better player with being a better leader. For one, Amare doesn't dance on the sidelines.
