Myers... I do not have a hand in who gets picked and as I understand it the selection for region 4 goes something like this (mind you I have no idea if it is true or not).
1- Coach provides a list of players from his team who he feels would be deserving of the honor
2- coaches then vote for the players from the other schools but not his own
3- the votes are counted
4- each HS is awarded nominees based on their finish

You can pick who you want to replace and there are certainly players who were not selected who would be deserving over others in a different school.
I have seen Daniel play and his importance to Irmo is clear. I would have thought that as an all state selection he would also be all region. Thus my question...

I am certain that had SA finished first people would be asking the same questions as they would have fielded the largest number of players.

If you have an issue as to who gets picked I suggest you take it up with the coaches.
