That is pretty much what XLV boils down to.

Packers= Classic NFL franchise, Aaron Rodgers, Happy for Green Bay, Mike McCarthy, Vegas Favorites, Media Favorites, Packers storied history, 12 championships. Almost EVERYONE is behind the Packers.

Steelers= Classic NFL franchise, Bad boy Ben Roethlisberger, Vegas and Media Underdogs, NFL Pariah, Roger Goodell hates them especially James Harrison, Hines Ward reviled, Sour Grapes from opponents.

I don't mind rooting for the villain for once, though. They get all the cool stuff.
