The ref crew doesn't make the call. nFL officiating head quarters makes the call. Also, it's where the first body part hits on a dive, not specifically where he starts the dive.
Here it is. The guy gets there in like 2 seconds. I don't know if you can really blame Stroud for that one. The play call shouldn't have been a seven-step drop out of shotgun.
I wouldn't call that a bad sack. He came out of his break and had 3 guys in his face. I don't know what you wanted him to do. That is a playcall failure.
There is literally no reason to throw the ball one more time this game. If you just run it 3 times in a row on our next 3 possessions the game is over.
