More often than not lately, there seems to be a huge difference between Duke's play in the second half of games and its play in the first half. It's almost as if they are playing two separate 20 minute games. One possible reason that occurred to me is that K could be holding back on aggressiveness in the first half in order to save fouls for the second half. Probably not reasonable speculation given that K has not been known not to be aggressive, ever.
