I can tell you - having been on headset for 100s of college games back in my day - these kinds of things usually would start being talked about once we crossed the 50. You would be talking about whether or not we should go for two, do we have a good two point play, will we win in OT, etc...
It blew my mind to see a delay of game in this situation. In fact, I don't think I've ever seen it. It was an egregious mistake. With regards to Dino throwing the blame on the players - Hey Dino, even if you weren't sure at that moment, what's the harm of putting 2 fingers in the air to keep the offense on the field so you don't have to worry about them not having urgency? Mind blowing stuff.
