Honestly, I am not going to expect too much betting on this series until someone returns, think about the game last night, its warriors and curry so we know they always have a shot at winning but they are also missing Klay and Durant which means they may not win the game, so of course people didn't really saw any clear winners on this game, raptors won but they won barely and we all know anything could have happened in this game too so nobody wanted to bet.

Wait until Durant and Klay returns and then everyone will be betting on warriors for sure, so much that the odds will be very low for warriors wins when they return. So at one side you have warriors with many injuries but still warriors, on the other side you have raptors who are currently beating warriors 2-1, who could you possibly bet right now?

KD still won't play by game 4 but Klay Thompson said that he's body seems feeling good and he's ready to get in for game 4.

But Klay Thompson is not 100% physical good like what he doing on regular season he can do both depense and offense while making score this is another adjustment for GSW this coming Game 4 if they cannot win on Game 4 I'm sure Raptor will be the champion this NBA finals, I hope KD will be back to play.
