I'd say they could tweak it a day forward or back but the tightly scheduled week makes that fairly impossible. I fear this one just won't be played, which stinks given it is a winnable home game for us and we are fighting for a MAC regular season title.
I've been wondering if the weather might eff things up for us as well. I think you can bet EMU will be on the road early wednesday before the rain turns to ice then snow. As long as the officials can get there (do they arrive a day early?), I figure the game will happen, even if it's friends and family. However, if students have classes called and have spent the day drinking anyway, maybe they'll take their pent up energy to the convo that night and make some noise. or look at their phones.
I would be more worried about WMU's travel on Friday when everyone is buried in snow, but I think the timing might just allow the games to be played.
