They were not major league teams, though
They should not be regaded as such.
Nothing wrong with accurate history.
Triple A quality? (During the era they played ball in)
MLB’s rationale was interesting. I wasn’t aware that the old pro leagues like the American Association and the Federal League were considered “Major Leagues” for record-keeping purposes.
Yes, as a matter of fact there is.
Depending on how these stats are reported, it could taint the
entire database.
Leagues play within a closed environment against a set ‘quality’
of other teams. When you toss in a non-like field of
competition, it skews comparisons.
Team X plays against 12 teams that eleven other teams play
against. In this closed environment stats are open for
fair comparison.
If you toss in teams that played against a different set
of leagues, with inferior or even superior competition, you
have just opened yourself up to making some teams and
players look worse or better by comparison.
