For those who follow the NFL, a very interesting event yesterday. Road teams went into this week 29 games over .500 ATS, an unprecedented record. This week, the home teams went 12-0, also an unprecedented record.

As to whether the 12-0 was the result of value having been built into lines distorted by the accumulated -29 record, I would say marginally. The power ratings used to establish NFL spreads don't really change much based on short-term samples, although whether half a season is short-term can be debated.

All in all, a tribute to variance, more than anything. Striking and unprecedented.
