The North Carolina Tar Heels have done just about everything you could ask a college basketball team to do. They wrapped up the regular season with just two losses. They got revenge for one of those defeats by beating Duke at Cameron Indoor Stadium in the season finale. And they regained the No. 1 spot in the polls heading into the ACC conference tournament.

All great from a basketball standpoint, but here’s what matters to handicappers: 20-8 ATS. That’s the third most profitable record in the nation. Still, we’ve seen this movie before. The Heels were ACC champions last year and a huge moneymaker at 19-12 ATS before March Madness, where they coughed up a big lead and lost to Georgetown in the Elite Eight.

This year’s team can also be beaten, as Duke and Maryland have already shown. North Carolina is ranked 23rd overall in defensive efficiency. Can the Tar Heels protect their Achilles’ heel this time?
