Rob Neyer notes today that every division is lined up correctly according to RD (except for the Dodgers & Giants). Reviewing the numbers, what stood out to me is that you've got 4 teams at -100 or worse (plus the Cubs at -98). And you've got 9 teams between -42 and 0. But just 2 teams (us and the Marlins) sit in the big gap (us at -76, them at -68).
Doesn't mean a thing; I just thought it was an odd distribution. The flip side is spiky as well: 4 teams (well) above +100, 6 between +53 and +80, then just 3 others in the green (including the Dodgers at +1, which may not last).
Theoretically, the middle group would be distributed about 0, but instead you have 10 clubs between -42 and +1, with gaps of 26 and 42 beyond that central group. My guess about what's happening is that the 4 monster teams have been so dominant that they've taken it out of the middling teams, such that an ostensibly .500 team ends up -10 or whatever because the Phillies beat their brains in to a greater extent than they could beat up on the Cubs (or us).
