The third time was not a charm. Late in the first half of yesterday’s game, the Blue Devils’ star shooting guard stuck his right leg out to trip Elon’s Steven Santa Ana. Allen then threw a tantrum on the bench after being hit with a technical foul. Duke’s dominant scorer tripped opposing players twice last year and earned an Atlantic Coast Conference reprimand. After the game, he apologized and choked up, but that was too little, too late. Coach Mike Krzyzewski called the move “unacceptable,” and Allen has been suspended indefinitely.
