I've mostly stayed away from totals this year due to the transformation going on with the scoring and line adjustments, but so far 'overs' are hitting at 54.3% in 2013.
A couple games stand out this week, which should feature a lot of points. Every single one of the following teams have defensive regression over the past few games, especially in the red zone.
Redskins/Cowboys Over 53.5
Colts/Chiefs Over 45
Raiders/Chargers Over 50.5
