Once again, his Duke Blue Devils (20-5 SU, 11-12-1 ATS) are experiencing a second-half swoon, going 2-4 SU and 1-5 ATS in their last six games. Duke’s defense has gone kaput during the past three contests, allowing the over to cash in every time after what had been a dazzling 10-1 streak for the under.

Good thing for the Blue Devils that they’re taking a break from the ACC grind and playing their annual matchup with the St. John’s Red Storm (12-13 SU, 7-11-1 ATS) Thursday night at Madison Square Garden. The Red Storm have dropped five straight to Duke – with the under getting paid each time – and failed to cover in both 2007 (+7.5 at MSG) and 2008 (+23 at Cameron Indoor). St. John’s has also lost its last four Big East games at 1-3 ATS. Get all your NCAA basketball lines in the Bodog Sportsbook.
