March Madness is known for upsets. It wouldn't be madness if it didn't contain upsets.
As some people worry about upsets in their bracket, there is also an upset-related related stat that impacts spread betting.
Over the past decade, top-25 teams in the AP Poll have gone 43% against the spread when playing against unranked teams in the NCAA Tournament.
That means a $100 bettor would be down around $10,000 if he bet on every ranked team playing against unranked teams in the NCAA Tournament over the past 10 years.
Let's take a look at the teams and odds that will fit this criteria in the first round.
