Fox may not have the games to sell viewers like ESPN/ABC and CBS does, but they do have two very popular personalities to sell – Gus Johnson and Erin Andrews.  After a quiet year of calling games on mostly FX, Fox is still betting heavily on Johnson as "The Gus Effect" is the centerpiece for their new college football ad.  Gus Johnson makes any game more exciting, but if he can really bring dancing ladies, unicorns, and Erin Andrews to your living room, Fox will crush everyone in the ratings department.
