Which team in the NFL has the best momentum to "go all the way"?

The team on the best win streak right now is Indy. I don't care whether a win is impressive or down to the last second. A win is a win. Sometimes a team you think isn't that tough can be hard to beat when the week before they were easy to beat. Look at Houston beating Tennessee for example and Dallas knocking off the Giants. What I like about Indy this year is that they are now winning games, even the tough ones like beating Pittsburgh at Pittsburgh, beating the Pats, and beating San Diego on the road. Those are normally tough teams they have trouble with. They know how to win close games and I think that will give them momentum in the play-offs. A team doesn't have to win by 20 points to move on in the play-offs. They just have to win by at least 1. The Colts have proved they are good at winning by at least 1.
