If you put money on one of the top seeds to win the 2019 NCAA men's basketball tournament before the competition began, your bet is in good shape.
Since the tournament has been dominated by top seeds, it might be worth doubling down on your pre-tournament wagers ahead of the Sweet 16.
Duke is still the championship favorite, but its odds are still favorable enough to consider a second bet to reinforce your belief in the Blue Devils.
There's also the option to put money down on teams that looked strong in the first two rounds and convinced you that they are worthy of a run to the national championship.
