Yeah but the fact that they had the lead when he pulled the starters and more importantly that a win would have kept the Jets out of the post season is why he'll get killed if they come up short today.
It was only a 5 point lead, it was a very losable game for the Colts. Really in some ways Polian is damned no matter what, if they beat the Jets it “proves” they could have continued the perfect run, if they lose it “proves” they sacrificed the perfect run for nothing.
