I know fans have thrown things at BYU games in the past. I get that there is similarity between the incidents.
That's not the point of what I'm saying though.
The point is that at BYU they take measures to prevent that from happening (they have learned from the past). At utah, no such precautions were made (they have not learned from the past).
Somebody made the point earlier that the person struck by the bottle was standing at a point where the field goal net wouldn't have made a difference. After seeing the video of the indecent I can acknowledge that is probably true.
