I attempt to approach all sports capping from an actuarial basis, but none more so than baseball.
While there's no certainty how each team will do over the course of six months, there is imo, reasonable forecasting possible within established ranges.
We start with knowing that with maybe a couple exceptions, the best a team will do is about .600 (97 wins) and the worst a team will do is about .400 (61 wins)
9-6 of course breaks down to just 3-2
This is unlike basketball (and to a bit lesser degree, hockey) where the top teams will play over .700 (57 wins).
So, while I don't neccesarily endorse TECH1515's wording, he's not far off from how I start my review.
