I just checked my team's (admittedly abyssmal) batting stats against the expected stats for players who have used them previously, and have discovered that 8 of my 9 starters on pace for the worst offensive numbers in WIF history, and the other is very close. Is this an indication of something I did wrong with them, or some odd statistical anomaly? I did admittedly pick up players primarily for defensive purposes, but a .601 OPS is a bit surprising for a team.

Safeco?

Yeah, when you put a bunch of guys who don't get on base in Safeco, that's gonna happen.

That is a point. And indeed, it was Safeco. I think most of them had been used in several places, which spoke more to the "I screwed up" section than the "SIM hates me"

Well, certainly it's the reason they're all having their worst seasons, but it doesn't necessarily mean you screwed up.  That's to be expected.  If your pitchers are having their worst performances too, then you've got problems.     

I had a team like that and it was in Safeco, the odd thing was their road stats weren't that much better.  Sometimes life just throws you a sh**burger.
