By definition, the middle infield is conceding the run when playing back. If they wanted to go home, they would be in. Again, if you can name one time in the history of baseball that a SS came home after playing back (assuming the runner didn't fall down or something), then I'll say "fine."
OK, well, I'll drop it.
I think you're all very, very wrong, but at least there's a clear difference of opinion, so I'm not going to whine to WIS.
