Well said Rogabee, just a few comments:
Regarding the zone, it's rare at this level for a team to play so simple a 2-3 zone without matching up, or setting traps in the corners or sidelines.  The zone was less complex than many I have seen in High School.  I agree with the point regarding over-pursuit.  I recall seeing the ball entered to the foul line and three Dukes being occupied by the guy at the foul line; but not to the point of making it difficult for him to easily reverse the ball through the post for a wide open shot.  Also, our bigs to creep out away from the basket and allow someone sneak in behind the zone for a layup. 

I posted my lengthy thoughts on using the defense to create offense prior to the SFU game so I won't reiterate.

We had to have gotten killed in the "hustle stats".  Loose balls recovery seemed to be heavily in favor of SFU. 

Yes, we got killed on the boards, but at least a few times I watched our guys occupy all three key rebounding spots, left hoop, right hoop and front hoop, and still fail to get the rebound.  It tells me that it's more than just boxing out, it's anticipating and moving quickly to the ball.  It's also about putting a body on people, and holding or expanding your rebounding "neighborhood" when the ball goes up.  I think we had position many times, but got pushed under the basket; which is just about being more physical.  The refs really called almost nothing in this game; so the more aggressive team was going to win most of those battles.  When teams are shooting a lot of three's long rebounds must be anticipated and you need to get a share of those.  Our guards did get the lions share of our rebounds so we probably held our own on the mid and long range rebounds.
