I think that the vast majority have full eyesight function and keen olfactory abilities as well. Have not heard that today would be any different than any other.
Was in a bling during last week's game (I know, I know, it was an annual family thing). Network connection sucked, so I had to watch the play by play in ESPN app. Prayed to God the app was messing up when I kept seeing us within their 10 yd line, then next play is "Iowa State 1st and 10 from TCU 30".
Needless to say no deer came near the that yelling.
