Three numbers that strike me as interesting about the 5-0 Tennessee Titans:
Tennessee's defense is allowing a league-low average of 11.2 points a game, over four points a game better than the No. 2 team (Pittsburgh, 15.8). The Titans play at Kansas City on Sunday, and the Chiefs have managed only 13 points a game.
The Titans rank in the top 10 in 13 of 17 defensive categories. Only Baltimore matches that and Philadelphia and Pittsburgh (12 each) are the only other teams in double digits.
While they're the only remaining undefeated team in the NFL, the Titans are talking about the areas where they can still improve. First down offense can certainly be better. The Titans are only 29th with an average first-down gain of 4.2 yards.
