ProFootballWeekly.com has TFL stats for individual players (pick a player and click on the "Splits" tab) but I couldn't find it for teams. It shows Mario having caused opponents to lose 96 yds. from 12 sacks and 6 stuffs (a tackle behind the line on a rushing attempt). James Harrison had 120 TFL yds. from 16 sacks and 3 stuffs.
