After the loss to the Baltimore Ravens, followed by a loss for the Kansas City Chiefs, the Chargers still have a chance for the top spot in the AFC playoffs. However, it will require both a Chargers win and a Chiefs loss. The Chiefs loss seems to be unlikely, as they will play the lowly Oakland Raiders.
This creates a unique situation. Getting a playoff bye week is important, as the last team to win the Super Bowl after playing on Wild Card weekend was the 2012 Baltimore Ravens. However, as mentioned above, a win is unlikely to get the Chargers into the first seed.
