So there you go Tommy every single game where the favorite was losing at the half since week 2.
10-10 on the year or 9-10-1 depending on the 2H line you got with New Orleans.And if you add in week #1 which it went 1-5 you would have a 11-15 record.....so weather you throw out week 1 or not, either way it is a losing system!
