This is exactly what happens when coaches vote. The coaches and league reps work together to generate a list of names from each of their teams. The coaches are then presented with a list. From that list coaches can vote for names of anyone except their own players for whatever criteria they choose. If they feel like more balanced representation is important, if they feel rewarding seniors is more important, if they don't like a particular players game or teams style or attitude they have no requirement to vote for them regardles, etc, etc.
Voting is winning Donald Trump a potential position of influence.
Voting gets us all these politicians we don't like 3 years later.
Voting is how in a house with more XX then XY chromosomes we don't watch a lot of westerns on movie night.
If you lined up all the players and evaluated them based on talent by commitee for an allstar or team selection: You would have lots of kids in the NE levels getting replaced by kids who were passed over this time in the SW. If you didn't have A-AA-AAA division assignments you would have whole areas and school sizes receiving no ALLSTARs.
The names you get are an accurate representation of what the coaches in those conferences wanted as a collective averaged out.
