The Oklahoma City Thunder are one of the biggest betting favorites in an NBA Finals across the past 20 seasons. The Thunder opened as -750 favorites over the Indiana Pacers in the Finals at ESPN BET. The Pacers opened as +525 underdogs on Saturday. Since 2005, only the 2017-18 Golden State Warriors (-1075 versus the Cleveland Cavaliers) had shorter odds heading into the Finals than this season’s Thunder.
