It's not inconsistent. What we're attempting to do here is find an objective answer. What is not black and white is the process. You are (as usual) interpreting what you want. Also, the age argument is invalid. It balances out because as some players get past their peak, some reach it. So that isn't so easy to identify in a black and white manner either.
Baseball, as a sport, is not a business, so while sometimes it is pertinent to apply business precepts to baseball analysis, it is not pertinent to apply it in this discussion. The results of a baseball season have too many confounders to be painted as black and white, which was my point.
Again, the 2006 Cardinals won it all, and they were not the best team in the playoffs. This is not even debatable. So can you say they were the best because of the results? That's why you need to eliminate the noise when making an analysis like this. Same for the 2003 Marlins, the 2008 Phillies and several other teams.
