Any idea why KC-DET is more likely than KC-PHI but the inverse is true (ever so slightly) for BUF-DET/BUF-PHI? Is it just random variance? Looking at the four teams' remaining schedules I would expect the AFC Super Bowl participant to be pretty independent of the NFC participant so I would expect the relative proportions of KC-DET vs. KC-PHI odds to be similar to BUF-DET vs BUF-PHI odds.
