These qualifiers add up to 16 spots, which I assume would be the "starters" on the east team. Now that the Diva event will act as a qualifier for one woman, this puts us at 17 total qualifiers. Which of the remaining qualifiers are going to lose a qualifying spot?
I wouldn't 'make the assumption that these will be the starters. Just as you have more people on teams, doesn't mean the first person chosen is the starter.
There will be a total of 21 spots available, as such the order may change even during the set up from the captains. To assume that these are the "starters" isn't accurate, nor has it been the "norm" Playing people against people and strength of games from time to time is important. Who is to think that a Captains pick isn't someone that they want in there immediately?
Captains decide the starting line ups, not the qualifiers.
