The Cavs have lost 10 straight regular season games against the Warriors with their last win coming on Christmas 2016. Their last win including postseason games came in Game 4 of the 2017 Finals. The Cavs are 2-18 against the Warriors since the 2016 Finals.
That said, we wouldn’t trade the 2016 Finals for anything. Hopefully this new era of Cavs’ basketball can rekindle the rivalry.
