Picking on Duren here because he just did it. But the entire team does this and it just mind boggling.
Duren stood there waiting for a rebound with his man a good 2-3 feet behind him. He didn't back up and close that gap between him and Gafford. Of course the rebound is long and Gafford grabs it with ease. Back into him and then you get that long rebound and if it comes off short you just step up and grab it. Always have your body on a man when a shot goes up.
