The difference was that was a night game. They're calling for scattered thunderstorms all day and the game starts at 11. They will continuously push this game back and delay it as many times as possible (like the Iowa game) until they can get in at least a half of football (a half must be played to count).
The teams and universities know this could get delayed, so they're going to be prepared for those delays by stocking up on extra food for their players to eat if there was a long delay. With how everything went down last year, Pollard is going to get this game in one way or another.
The forecast is calling for thunderstorms in the morning but then scattered in the afternoon. There's actually a pretty good chance that after the initial storms / rain, it clears up for enough time to start the game and get in the amount of time needed.
