Any award, selection or list is going to spawn debate.
It is hard for anyone to make a case for any player without first knowing the criteria from which the list is made. Do coaches get to nominate, do reporters vote, does most goals win for an offensive player, most shut-outs for a defender, is a state berth a pre-requisite, is it the performance for the season, their high school career or a marquee game, does a state title regardless of division give a player an upper edge?
Depending on which criteria you choose to look at, a case could be made supporting all five of the finalists, and they should be congratulated along with all the ALL-Metro selections. On the flip-side, the same argument could be made for several other players, and again...depending on the criteria, a case could also be made against most of the five finalists.
It shouldn't be about a school, or a state berth or a state championship unless the player being considered has a dramatic impact in those games that tilts the scale in their favor. This is after all an individual recognition and not a "school" award. Likewise, players shouldn't be picked just to give parity among the schools. In the future, perhaps dividing up between the city and county or public and private may better serve those distinctions and readerships.
I will agree, most of the elite players in the area know who they are and know each other. They don't necessarily need a formal recognition as long as they have the respect of their peers and coaches. I'm pretty confident the alternate names tossed out so far have both.
