Black Pants Lions vs Cowboys

[IceGator8]

I noticed the officials for this game are in the black sweat pants. Doesn't Detriot have a domed stadium? I thought the black pants were only for cold weather. Are the NFL officials finding that they prefer the black sweat pants to knickers and starting to wear them in the warmer games?

Frankly, I can see why they would like them better. Better layering options with enough extra room to move. Also there is no more dealing with referee socks or knickers. As an official with large calfs I hate the socks and knickers of my traditional uniform.

Anyway, I'm not baggin on tradition I just thought it interesting that there might be a possible trend.
