A case of food poisoning and lack of defense makes Duke an unattractive favorite. The Blue Devils lost at home to North Carolina in their final regular season game and were unimpressive in an 88-79 ACC Tournament quarterfinal win against undermanned Syracuse yesterday.

This is what Duke coach Mike Kryzewski said following the Syracuse game: ''We're not playing very good defense right now. We did not against North Carolina and we did not in this game. We're missing a lot of assignments. Kryzewski also said some Duke players were dealing with food poisoning.

Miami is 9-3 ATS as an underdog this season, including upsetting Duke, 76-74, on the road in January.
