it is extremely windy up here in NW Indiana today.....south wind between 20-30 mph (gusts to 40 mph) forcast all day.....that type of wind direction runs from end zone to end zone in ND stadium. I was at the tennessee game last week and we had the same wind direction but about half as strong.....it really affected punts and kick offs a lot. Don't know how this will affect the total today.....could be a lot of running going into the wind and a lot of passing with the wind? could make for some short fields as well.....good luck, just thought I'd pass this along in case you were considering either side of the O/U.
