It is crazy that the Chargers are scoring just over 4 points more per game than the Titans, and they are ranked 8th while the Titans are ranked 22nd. This game is a match-up of 2 pretty similar teams. Both teams run the ball well, haven't thrown it all that well, and play good defense.
The most impressive thing about the Chargers is the +14 in the turnover differential. They are 2nd only to the Patriots. It is amazing that they haven't won more games.
