It's just hard to watch a sport for 40 years where that isn't a penalty and then a new rule has you slow it down to where it becomes a penalty after the fact. I get it...it was Pass Interference, but you hate to see a non-call that was so fast in the moment go against you and literally cost you the game.
But also, it's a coaches job to advocate for his players. It shows them that he cares and expects the same from them.
ALL OF THIS.
There are penalties like this EVERY game that are not called. It was bang-bang play and if you watch in real time, you don't call that. These plays that are broken down, frame by frame by frame, yes you're gonna see a penalty.
I'm glad he was so pissed and let the officials know his opinion.
