They should be used only in extreme weather. I know, I know you have heard all of the stories about walking 2 miles to school barefoot in the snow (uphill both ways) from all of us old farts but I truly do not like the look especially when they are playing in 45 degree weather. The players are in short sleeves and the coaches in shorts while the officials are in long sleeves, black foul weather pants, head warmers, etc.
Like a wise man told me once................
"why do you work football games in the wind, mud, snow, rain, sleet, heat"
"Because the do not have domed stadiums in West Texas"
If it was easy, anyone could do it.
Ditch the black pants except very, very, cold weather.
