The NCAA tournament is always important for the teams involved, but it may be even bigger for office pools and sports books around the country.
According to David Purdum of ESPN.com, the American Gaming Association estimates 70 million brackets will be filled out to total $10.4 billion overall in bets.
The total money expected to be on the line is up 13 percent from last year's figure.
Darren Rovell of ESPN provided some perspective of the money involved:
Interestingly, only three percent of bets are wagered legally with $10.1 billion coming into offshore or local books. The $295 million expected to be bet at Nevada casinos is more than the $138.4 million gambled at Super Bowl LI, a new record, according to Purdum.
