Playing good Defensive for an entire game it's an act of your will. You must be engaged to be involved.
Melo is the leader of this team, but instead using his energy of diving out of bounds for loose balls (that was already out of bounds) he needs to use his energy to rotate over more and help protect the rim.
Too many times I've seen the leader of the team stand flat foot watching somebody blow right by him.
The coach and guys on the bench watch his inactivity on defense.
He only tries hard when the guy is directly in front of him.
Me thinks he played zone too much at the Cuse. LOL
