My sister made sure that her niece had the proper attire to be a Broncos fan - it worked! They won Super Bowl 50, or L, for the Romans in the crowd. It's interesting to think how football is changing. It could even have role models for her - just last year we had the first female NFL ref and assistant coach. On the other hand, maybe it will have drastically declined in popularity by the time she's older, because of the obvious and terrible health effects. We shall see.
