Watching these old Super Bowls on NFL Network, I am struck by a few things. First, referree mechanics have really changed an awful lot in the last 15 years, and for the good. What a mess things were back then -- guys running in from all over the field, Us calling touchdowns, line judges getting caught 20 yards upfield. Just a wreck to watch. Second, who ever first though to put the score and the clock on the screen throughout the game should win the nobel prize.
