If you had told me that at the end of the day today, there would be only one undefeated team in the NFL, I would have assumed it to be Chicago, meaning that New England would have beat the Colts.
New England put up a decent fight, but the Colts were consistently the better team tonight and remain undefeated. NE fans weren't too happy to see Adam Vinitieri kicking for the Colts now. Although he got two field goals, he also missed two, which is pretty bad for him.
Chicago, whom many had considered the best team in the NFL, lost to last-place Miami, whom many considered one of the worst teams. That leaves Indianapolis as the only undefeated team.
Buffalo had a good win over Green Bay, a win they badly needed.
