Vegas favors the Packers by a slim margin, but it's certainly tough to bet against the Steelers.
Ben Roethlisberger has already twice won the big game, and his postseason record speaks for itself. Pittsburgh's defense is also the league's best, featuring Defensive Player of the Year Troy Polamolu and a monster linebacking core anchored by James Harrison.
The Packers, though, have an elite defense of their own, with Defensive Player of the Year runner-up Clay Matthews, Charles Woodson and B.J. Raji among others. They also have Aaron Rodgers, a quarterback one win from joining Roethlisberger, Tom Brady, Peyton Manning and Drew Brees on the league's top tier.
In terms of weaknesses, Pittsburgh's cornerbacks are far from great and their offensive line is legitimately patchwork. Green Bay, though, lacks in the running game, and Mike McCarthy isn't the coach that Mike Tomlin is.
