This is likely a big factor, as the Patriots are 2-9 in their last 11 "back to back" road opportunities.
It also should be noted that even our regular road record isn't as hot as you'd think, which is common for NFL teams, particularly when you win 7 or 8 games at home every year.
I believe that we're 10-8 in the last 18 road games, losing 3 last year and 5 (every single loss including the AFCCG) the year before.
I'd have to guess that these 2 factors, combined with IND's 3 straight victories are lowering next week's futures line a bit.
