Cavaliers winning that game is not because they are lucky. It's a clear upset and congrats Cavs for that.
A 9-15 Spurs and a 6-19 Cavaliers do have a large distance?
This game is like what happened to Miami Heat vs Atlanta Hawks last December 11, 2019.
The whole team Atlanta Hawks thought the game is over when they lead 6 points in the last 1 minute. But the Heat comeback a win in overtime.
I think it's different because in this game the Spurs are the favorites and they loss.
In the game between the Hawks and the Heat, it was the Hawks who are in control in the game but then they allowed the heat to come back and they beat the hawks in the OT and also covered the spread, I'm sure bettors are so happy with what happen.
Spurs vs Cavaliers - underdog won
Hawks vs Heat - favorites won.
