The Indiana Pacers are the biggest Finals underdogs in 20 years at 5-1, but they are receiving strong support from the betting public. ESPN BET reported Thursday that 78 percent of the bets on the series winner were on Indiana, while nearly 90 percent of the money that had been wagered was on the Oklahoma City Thunder.
In order for a bettor to win $100, they would have to risk $700 on the Thunder.
The Detroit Pistons were also 5-1 underdogs in the 2004 Finals against the Los Angeles Lakers, which they went on to win in five games.
Shai Gilgeous-Alexander is a -550 favorite to win Finals MVP.
