Now you are just being funny
It's a given that not all the players on a team are going to be available for every match, for various reasons - vacations, injuries, sectionals, family commitments, whatever. That's why teams typically have anywhere between 12 (aggressive) and 20 (conservative) players when only 8 are needed per match. Managing around player availability issues is part of the captain's job. And having depth on a team is as important as having a few strong players. Otherwise, why bother having any more than 8 on the roster?
Since you have repeatedly voiced your displeasure at teams who employ ringers, I'm surprised that you would take the side of teams who are top heavy and ride the ringers versus teams who are solid all around and spread matches across the roster.
