Otherwise, even more skilled teams, like the Cardinals of the past would have won 115+ games annually. They didn't because a large sample will weasel out clearly ridiculpus stats with no merit like those shown in this thread.
How do you know that the Cardinals during Rolen's weren't really 80 win teams without him?
This is pure speculation, but one factor may be that having Rolen in the lineup changes the way that pitchers approach the other players? I don't think we have to dismiss this effect as magic or luck just because we can't find a specific stat to tie it to.
