When it comes to ranking pass D in the league, people usually only look at passing yards given up. However, that can be skewed by a lot of things...field position by opposing team, pass attempts, and if the opposing team is playing from behind.
So, the Titans currently have the 23rd ranked pass defense in terms of yards per game (231 ypg). Based on that stat alone, most people would think the Titans pass D is mediocre to poor.
But, the Titans have the 10th best pass defense in terms of opponents' yards per attempt (6.6 YPA) and 9th best pass defense in terms of opponents' passer rating (74.5).
Add in the league leading 24 sacks and the second-best team in interceptions (10) and this pass defense is 100x times better than last year.
Last year, we were 31st in yards per game (259ypg), 21st in YPA (7.2 YPA), 25th in passer rating (91.2), 18th in sacks (32), and 8th in interceptions (20).
Give Cecil some credit along with improved secondary play (thank you Griffin and Verner) and improved pass rush (thank you Babin, Ball, Witherspoon, and Jones).
