First round opponent: Cincinnati Bengals Why they're dangerous: The best passing game in the sport, playoff and Super Bowl tested coach-quarterback combination and nothing to lose after being declared dead multiple times this year. Why they're vulnerable: Very reliant on a passing attack. Can that hold up in the cold of Cincinnati, Denver and New England in consecutive weeks on the path to Santa Clara and Super Bowl 50? First round opponent: TBD Why they're dangerous: A dominant defense, deep crop of players left from 2013 Super Bowl run and Peyton Manning.
