It all comes down to scoring with this team. Wall and Young were 20+ points and McGee put up another double double. As a result we're a three pointer from Carmelo (that he got off because he elbowed singleton in the face) away from winning. Mid 90s scoring is typical for teams to win. You aren't going to see a lot of 87-83 victories from this young team.
They have to keep it up and others have to improve.
