If I'm losing by 8 with 2 minutes to play I want to play aggressive tight m2m but not foul and not really guard against the 3 should I play + or down by 8 with 2 minutes to play play - because the other team is not looking for the 3 point shot?  If I play - then they can run out the shot clock, but I protect against the inside which they are most likely going  to look for better % of a shot.  Does + always mean protect against the 3 or can it mean at end of game just be more aggressive?
