The Divisional Round of the 2013 NFL Playoffs begin in just three days. Three of the four games feature rematches from the regular season; can Baltimore head to Denver and avenge their Week 15 blowout loss to the Broncos? Aaron Rodgers and the Green Bay Packers are San Francisco-bound with revenge on their mind ever since the 49ers won their Week 1 matchup in Lambeau Field, while the Texans look to atone for getting clobbered at New England in Week 14. Seattle will travel to Atlanta to take on the Falcons minus Chris Clemons, their best pass-rusher. What impact will that have and what are the keys to the games on Saturday and Sunday? Dan Rubenstein and Matt Ufford of SB Nation break it down.
