The way the big meets are run is why they now have the selection camps. The old method of taking only AA gymnasts to meets is no longer the best way to put togther a team. 3 up 3 count for scoring, with only a team size of 5 makes running these camps and the way the staff puts togther a team necessary. They will take the top 2 AA gymnasts, and then they put togther a team of girs that can potentially give the highest score for the 3rd spot on each event. Your work ethic, past performances (consistency) and other factors are also taken into consideration.
Its not about favorites per say, but about them trying to put together the team that they think will have the best chance to score. If they took only the top AA, Alicia Sacramone would not be going to worlds, but a weaker AA gymnast who would definitely not score as well would be. The point difference between #1 and #10 in the all around at Championships was way over 10 points.. . Do we really want the person in the #8 spot (if gymnasts #6 & 7 happened to be injured) going over someone who can potentially win a world medal?? While it stinks to be the #8 athlete/coach, USAG is all about winning at the elite level, and winning is why they invest so much money in the camps & the training center, and what they hired Marta for.
The true downside is the fact that the girls need to keep pounding to show their readiness... so its not the fact that thay have the camps, but how they are run that is the issue. That is why the smart coaches did not have their athletes do AA at championships (if they were truly in contention for worlds) if they have some type of injury-they know there is a lot more to come and the camps are where they have to prove themselves. They really know who will be on the team right now, but they do the camps as the Olympic committee says they have to. All the athletes, parents & coaches have to sign an agreement that they understand & accept the process if they want to be in contention for the assignments.
Hope this insight helps.
