Sometimes you witness moments in athletics that you know are great. The Flea Kicker, the Miracle on Ice, the Immaculate Reception, etc. Then, there are times when you witness something that you suspect is not only great, but will change a sport completely.
Such is the dominance of the U.S. Women's gymnastics team.
I am a very casual gymnastics viewer. I watch every four years at the Olympics and that is about it. In other words, this is your heads-up on the level of "expert" analysis you are about to get.
Not so long ago, Russia and Romania were dominating women's gymnastics with teams of pixies that were graceful and would look as comfortable on a ballet stage as a gymnastics apparatus.
