I think game week, you prepare the same as every other game. Same schedule, same routine, same game day routines, etc.
The one area I diverge is that some games just are bigger. They carry more emotional weight. And not at least discussing or preparing your team for that is a problem.
Games against Utah, USU carry more emotions. You gotta prep for that to turn it to a positive, or the opponent will and can use it to their edge.
