As any competitive athlete would likely be, Briana Scurry wasn't happy about being left off the Olympic roster. She said as much to certain media.
Another coach might have taken offense to being second-guessed, might have avoided working with Scurry or deemed her presence a negative distraction to the players who were picked over her.
Pia Sundhage named Scurry to the alternate list. Scurry is actually in China, training and traveling with the US women's squad, though obviously unlikely to take part in any games. "Force majeure" would have to happen first.
Scurry worked long and hard for her opportunity. She's not getting a chance at Olympic gold because sports is a tough world where cuts have to be made. She was upset and she said her piece.
As far as I can tell, Pia didn't take it personally. She moved on.
