My team's Expected Win % is .453, but my record is .377, an under performance of ~.075. Last season I outperformed this measure by .041. My other two seasons I was within a few percentage points. I'm not too worried about it, because I understand there's quite a bit of luck involved.
However, does anyone pay attention to these numbers? Does it mean much to anyone if you're over or under-performing? It made me wonder if there were team management (or better coaching) settings that might affect something like this? Just curious.
