Power 5 dark horse teams

— -- Katy Perry likes a good dark horse.

So does college football.

There are numerous scenarios that could still unfold in the College Football Playoff race, and the pool for candidates is still deep -- like, top-25 deep. There are a few teams, though, that have started to raise a flag, saying, 'Hey, look at us!'

With so many upsets in Week 6, doors to the playoff have opened in every conference. Here's a look at one Power 5 team in each league with an outside shot at playing its way in:

ACC --  Georgia Tech :  Everett Golson has made enough plays to put his team in positions to win, and he's the kind of mobile quarterback who can give Florida State's defense headaches. Notre Dame has gotten to this point, somehow, in spite of many questions and an academic investigation that has sidelined five players.

Right now, the Irish are in the conversation. If they beat Florida State, they should be in the top four.
