I thought in real time it was a clear penalty, but then, when you watch the replay you see that Hwang never touches him. He just scuffs the ground and the Cheat player trips on his own foot. But, am I surprised that VAR can't see that?? What is the point of have Video Assist if even then they f up the decision?
But actually, Hwang sort of deserves that for dicking around with the ball in his own box instead of just booting it to safety. What the hell was he doing?? (He never makes those mistakes against us mind you.)
The NBC announcers are trying to walk a fine line by saying... "well, if you're attacker, it's a penalty and if you're defending, it's not." The commentators first reaction was... "no, I'm not so sure there's anything there..."
