2015 NBA Champion sports book odds
Las Vegas sports books quickly adjusted their odds to win the 2015 championship. The Las Vegas Superbook made the Cavs the outright favorites at 3-1, while dropping the Heat's odds all the way down to 100-1. The MGM moved the Cavs down to 7-2, co-favorites with the Spurs. William Hill and the Wynn sports books both moved the Cavs to 9-2.
Two months ago, the Cavaliers could be found as high as 60-1 to win the title, but money poured in over the last three weeks after James opted out of his contract with Miami. While the majority of wagers were small in size, the MGM, Nevada's largest sports book, told ESPN.com that it took a $1,000 bet on the Cavs at 40-1. Sports book operator CG Technology said it took "some higher dollar amounts from respected guys" on the Cavs at 30-1.
