Since then, the odds have shifted more in favor of Golden State, who is now -300 to claim the NBA championship, while the Raptors are up to +240, per Westgate.
Despite being favored to win their fourth title in the last five years, the Warriors are one-point underdogs in Game 1 on Thursday at Scotiabank Arena in Toronto.
Durant suffered a right calf strain against the Houston Rockets in Game 5 of the Western Conference semifinals. He missed Game 6 of that series and sat out all four games of the Warriors' sweep of the Portland Trail Blazers in the conference finals.
The team announced Thursday that Durant is "unlikely" to play in Game 1. The Warriors have posted a 31-1 record in their last 32 games when star guard Stephen Curry plays and Durant does not.
The Raptors fell into a 2-0 hole against the Milwaukee Bucks before winning four straight to clinch the Eastern Conference finals series. Toronto advanced to its first NBA Finals in franchise history with a comeback win in Game 6 on Saturday night.
Toronto won both regular-season meetings against the Warriors this year. The Raptors edged the Warriors, who played without Curry and Draymond Green, in overtime 131-128 on Nov. 29 and 113-93 at Oracle Arena, without Kawhi Leonard, on Dec. 12.
