DURHAM, N.C. — No. 1 Duke entered Saturday’s game with Maryland coming off a 27-point embarrassment at Miami, the worst loss by a top-ranked team since 1968. And so the Terrapins, pregame narratives read, would simply be the helpless punching bag, catching the Blue Devils at home on the worst possible afternoon. That this young Maryland team traded blows throughout the first half was surprising enough, as it entered the break just eight points down without freshman guard Seth Allen, who was benched for disciplinary reasons related to a missed team meeting. And it took some time for the rout to ignite – until the second half, even – but the Blue Devils finally pulled away for a comfortable 84-64 win Saturday afternoon.
