Rebounds are the biggest problems the Nuggets have.
They've been out-rebounded each of their 3 games this season, and having a duo of guards who are just barely over six feet tall is really hurting them. For a 7-footer, Nene should be averaging at least 8 or 9 boards a night, not six or seven.
Karl has to preach crashing the glass to this team. Good boarding is critical to starting the fast break.
