Only the Super Bowl remains in a very surprising regular season. The San Francisco 49ers are a force to be reckoned with in the NFC, finishing 13-3 in the regular season just one season after finishing 4-12.
Meanwhile, in the AFC, the everlasting New England Patriots and the number 1 seed, the Baltimore Ravens, have both been surprisingly eliminated from contention at home by the same team, the Tennessee Titans.
Looking at the four teams that qualified for the conference championships, this is a perfect time to evaluate what made teams successful this year, and what can the Chargers learn from them.
