Not at all. Obviously, playing against the same teams with mostly the same roster is going to produce the same result, if everyone who comes back to the team improved by the same amount in the off-season, and the new players to the team are of the same skill level. While the correlation is probably there, I'm not sure how strong it is.You're going to need to clarify this. Do you mean for any randomly generated team? I might agree with you there. I haven't looked at the historical spread. But that isn't at all what this discussion is about, so I'm assuming you mean for a specific team. And that would be 100% wrong.The odds of every game ending in a loss is the same as the odds of every game ending in a win. They're opposite sides of the same coin.
For starters, I never said or implied the bold comment. I was talking about regression toward the mean, which is entirely different.And our disagreement is probably due to the "scope" of how we're wishing to make these predictions. I think you're going from a more holistic approach and seeing that a) we've overachieved according to the PF-PA differential and the projection for wins and predicting b) that we're going to eventually underachieve, which isn't what we want.
I'm taking a more specific approach and treating each season as separate from the season before because I think there are so many extraneous variables that factor into wins and losses that can not be controlled, so we can't look any further than just one year.
The disagreement lies in the fact that your second paragraph is just not true. Are you honestly telling me that the result from last season - a season against likely the same teams, with about 75% the same rosters - is completely uncorrelated to the result of the next season?
I get what you're saying now, that as sample size increases the distribution approaches normal, about the mean.
What I was saying in that first paragraph is that, all things about each team being equal, the chances of every game being a win are are the same of every game being a loss.
