It's time to preview the ACC / Big 10 challenge! We look back at all the Tropical Tournaments and ask ourselves: what do we know about this year of college basketball? Then, on to the main event: the ACC / Big 10 Challenge. Louisville takes on Michigan, the hottest team in college basketball, while Duke tries to gut it out minus Cassius Stanley against Michigan State. The team decides that the Virginia vs. Purdue game might be the lowest scoring game this year, and the UNC vs. Ohio State matchup might reveal a secretly fraudulent top-10 team. Plus, Florida State vs. undefeated Indiana, Notre Dame vs. Maryland, and all the other matchups picked against the spread.
