Rookie of the Year odds
Caesars posted ROY odds on June 18, two days before the 2019 NBA draft. As the projected No. 1 pick, Williamson opened as the prohibitive odds-on favorite at -450. "Zion is a giant favorite, but I don't know if it's big enough. It's one of those things if I take a max bet, then I might go [much higher]," Caesars head of risk Jeff Davis told ESPN at the time. Memphis Grizzlies guard Ja Morant and New York Knicks guard RJ Barrett had the next-best odds at +450. The three represented the top three picks of the NBA draft.
In his fourth preseason game, Williamson apparently injures his knee and several days later it's announced that he will miss the start of the 2019-20 season with a knee injury. Morant becomes the betting favorite on Oct. 29, with Williamson falling to the third-best odds.
