Another problem is East one day and West the next. If West people vote and an East owner feels he is being shortchanged by a west GM. There could be just enough of a lowering of his seed by the east GM vote to hurt a west teams playoff chances.
Of course, what I think is trying to be stopped is that perceived really good teams don't get screwed but by the same token there can be plenty of retaliation voting for the teams in the middle that could keep a team out of the playoffs.
For instance, my team I think will not come close to winning my division but should, IMHO, make the playoffs. But if I vote early and anger some of the teams I am in competition with, some or one GM could put my team down around 13th or so and that one vote could keep me out of the playoffs. And, my guess is someone could come up with enough BS explanations to rank any team 13th in the conference. So the vote would probably have to stand.
For that reason, I'm not voting until there's about 5 minutes left before the vote deadline. If people can't see my vote until just before the deadline, they can't let my vote influence their's in time.
