INDIANAPOLIS - When Tyler Thornton came off the bench for Duke he knocked down a three pointer in short order.  As it turned out, the only points Thornton would score but his defensive play was crucial in the Blue Devils 71-61 win over Michigan State.  Thornton had two steals and he played a solid floor game in his 26 minutes.  While he was no the star of the game, his play was critical in helping Duke advance to play Louisville in the Elite Eight.
