The only thing the Colts defense has going for them is the Colts offense. They do not force their D to be on the field for many consecutive long series, they score points and force the opposing team to be more aggressive, and give there D good field position. So the fact that Brady still marched it down there throat shows how worthless they really are.
They got out coached and simply do not have the players because all the team money is on the offensive side. I would bet they only have three games where they keep the opposing team under the league average this year in points.
