Weirdly, I think this team was actually constructed in a way that protected it when this happened. By taking the top 4 AA scores, the "team" was set up to compete if Simone wasn't there. If say a beam specialist who was terrible on bars had been chosen, the result could have been worse.
Team USA definitely counted on Simone to win gold in the team and other events. I think her strength hid just how much the rest of the world was catching-up with Team USA. I'm just not sure that the team could have been designed better around her.
