You should care, because the argument you are trying to make is inherently flawed. Is there a correlation between Soriano's stats being better when batting leadoff, and worse when hitting in the middle of the order, yes. I would argue that it is a strong correlation, too. However, just because there is a correlation, doesn't mean that batting leadoff caused Soriano to have better stats in that role, or that batting in the middle of the order caused him to have worse stats. Is there a chance that it did, maybe, but it has not been proven. Several other factors could and probably do factor into these statistical differences. Therefore, correlation does not imply causation. That being said, I have no problem with Soriano batting leadoff.
