I’m with Kenny Smith.  I know that the zone has served Flip Saunders well, but in a situation like the one Detroit faced –- having to extinguish the most historically unconscious blitz in recent memory  -- you have to be able to exert better control over your defense.  When you’re in a man-to-man, who collapses and when they collapse is a decision of the individual and not the system.  When you have good individual defenders as the Pistons do, that's an advantage you want.  It’s the difference in control you have over your terrian when driving an automatic transmission versus driving a stick.  In a zone, the station of the ball generally dictates the defensive scheme.  A weak-side defender in the zone can’t say, “You know what?  Right here is the instant I should slide over on LeBron.  I've watched him for three possessions, and this is the precise spot he goes from second gear to third.  But if I step in right now -- not a half-second from now, and not a second from now -- but right now, then--”  Too Late.  Driving slam.  Even the Pistons, who instill a great deal of improvisation in its zone, can’t give an unconscious assassin on his best night the attention he requires, unless they’re in a man-to-man.
