It's pretty clear if the season ended today that these Colts can't make it to the Superbowl, and certainly won't win it. Clearly, they're on track to win their division (only 6 games back with 7 games to go, one of which is against the Texans, so that's like 2 games). But let's look at the playoff picture.
We probably have to assume for now that they are not going to get a first round bye - maybe I'm wrong there. Wildcard weekend, they would face the Steelers. They've already, basically, proven that they're better than the Steelers, but in the playoffs you have to be able to stop the run. The Steelers smash-mouthed football beats the Colts again in the playoffs. Even if they luck into the Ravens, same story. If they manage to somehow sneak past the first round, this team has shown enough stuff in practice and during press conferences to beat average teams, but not the perennial powerhouse Bengals they are likely to face in round 2.
So, one and done, maybe out in the Divisionals. Squash those Superbowl hopes right now so you don't get emotionally destroyed in the playoffs. Same old Colts.
