From 2004 to 2013 the Pittsburgh Steelers only had one season where they weren’t a top ten defense in yards per pass attempt, and were either first or second in half of those years, the only season they weren’t top ten was in 2006, when Ike Taylor was benched during the Super Bowl hangover season.
From Ike Taylor’s second season to his last as starter, the Pittsburgh Steelers were top ten in yards per pass attempt allowed. They fell to 29th in the NFl in 2014, Dick LeBeau’s last year with the Steelers.
They improved from there and in 2017 would rank 11th in yards per pass attempt, in 2018 they would rank 7th, in 2019 3rd and in 2020 2nd.
