Go ahead and call me a semantic nazi. I don't care.
I've been watching American football games for over 60 years. It was always the rule that the coin toss winner chose to "kick" or "receive". "Defer" was never an option. It's nonsense.
You will never see any team running their "defer" play to start a game, or practicing their deferrals. What you will see is one team kicking and one receiving.
Why has this suddenly gone beyond the understanding of NFL officials and announcers?
