You cannot? Somebody should have told me that before I started college! (Heck, we used to do shots on the way to the game! Everytime the bus went into a tunnel we’d shout “Eclipse” and throw back a Prairie Fire (Jack & Tabasco).
A good College Hoops stats site! An important stat to watch is %FG (FG made / FG attempted). That’s telling you how well a team is shooting while playing.
Team Opponent Percent of Points from 2 Pointers is an indicator of the close-in defense but does not take into account 3 pt shots and free throws. As far as defensive stats go, I look at turnovers and defensive rebounds. You also want to look at the fouling averages since while you may be defending well, if your are doing so at the price of more fouls/game it probably isn’t getting you anywhere.
Scores from turnovers is a good indicator of how well a team is playing on both defense and offense.
I previously mentioned VU’s emphasis on 3pt shots. From the stats site, they are #4 in 3 pt attempts (29.8/game) and #5 in 3 pt shots made (11/game) . So on average they are scoring 33 points/game from the 3 pt line. I think that tends to spread a defense…guard against the 3 pt threat and you are more open to allowing the opponent to get to “the paint” for higher % 2 pt shots.
The only things that prevented me from playing college basketball were talent, skill and height…although I was pretty good at the moving screen (which unfortunately is a foul). 
I’ll wait until March Madness then start a College Hoops thread. I’ve really enjoyed this thread. Hopefully we’ll see some more posts at Draft time.
