If you could change one thing about Equipment/Uniform...

The pants should be an option. As we get used to seeing them
on Sundays, they may become acceptible in some form. They would
probably have to come in a different look so as to not infringe on
any NFL copyrights. I still use an Acme pea whistle !
A "C" on captain's shirts isn't practical as many team captains
change game after game. Same for the letters on the back of
official's shirts--many guys change positions.
