Josh Sitton is just the third Packers guard in the last 40 years to make the Pro Bowl.
The late Gale Gillingham and Marco Rivera are the others. Over the last two seasons, Sitton has established himself as an elite pass-blocker and cornerstone of the Packers' offensive line. With Evan Dietrich-Smith stepping in at center and T.J. Lang emerging at left guard, there's reason to believe this unit can have a bounce-back season in 2013. They allowed Aaron Rodgers to get sacked a league-high 51 times in 2012.
