The contrast between the remaining 3 teams in the NFC and the remaining 3 in the AFC, is pretty amazing.
The three remaining NFC teams are defensive powerhouse teams, with good running games and mobile QBs who can make good throws when they need to.
The three remaining AFC teams are great pocket passing teams* with questionable defenses.
*The fact that the Patriots have been a very successful running team, that also happens to have one of the all time best passers under center makes them the most dangerous team in the AFC, imo.
