--The stirrups over the white sanitaries.
Hah. How about:
White crew sock over the black stocking?
Life before bean bags?
Life before the restricted area?
Life before play clocks?
Life before the 3 and 1 principle?
Life when DPI was a spot foul?
Life when they could send out unlimited numbers for the coin toss?
Life before the fair catch?
Life when they could use a tee on FG attempts (not all that long ago)?
Life before the 9-yard marks?
Life when there were limited substitutions (in my high school playing days; not since I've been wearing the stripes)?
Square-toed kicking shoes, and straight-on kickers (Lou Groza, Tom Dempsey)?
I could go on, but I won't.
