I don't think this performance should be all that surprising. Like it or not, FVV was kind-of right - the Cs handed them a free win and in turn left the series wide open. Guys can say all of the right things before a game like this, but the human psyche can be very powerful. It's very easy to see how losing a game like they did on Thursday - a historic loss - would lead to an additional loss.
We were lucky to be up 2-0 in the series at the time, because this series would likely be over with at this point otherwise. They - especially Brown - need to get their heads out of their butts and start playing with determination on both sides of the ball. TOR is only going down if we beat them into oblivion. This Cs have been frontrunners for years; they need to prove they can fight back and re-gain control of a series. TOR is nothing w/o Kawhi and the Cs need to believe in themselves again. Otherwise, we are essentially going to be the 2020 version of Sixers confetti game.
