Every year when the NCAA Tournament rolls around, the same assumptions are made about the same teams.
"Tom Izzo always dominates in March."
"Duke is prone to an early upset."
"Don't bet against Kansas in the tournament."
"Gonzaga doesn't play anyone in the season, so it'll struggle early."
We have heard them all. But how true are these assumptions?
We used our Action Network Labs database to figure out which programs have been the worst teams against the spread in the NCAA Tournament since 2005.
