Nebraska was in the same situation. The Texas Tech at Oklahoma game, maybe 8-9 years ago, which completed ~ 5 am the next day, apparently resulted in limits to these type of delays. It seems straightforward enough to establish some "practice facility rules" that would allow completing a game in an adverse weather situation. For instance, a punt could be a 40 yards position change, but no deeper than the 20 yard line. Other problems easily solved would be the need for players to change shoes from natural turf to field turf, camera angles, and instant replay. These type of things are very low cost in comparison to the value of completing a scheduled event of this magnitude. And it wreaks of common sense.
