In their Week 13 matchup against the Washington Football Team, who entered the game sporting a 4-7 record, but maintained the league’s second best pass defense with a ferocious front four, the Steelers allowed a 14 point lead to evaporate, suffering a 23-17 defeat, their first of the season. Entering the game missing key defensive pieces in Steven Nelson, Bud Dupree and Devin Bush, in game losses to Robert Spillane and Joe Haden proved costly down the stretch. Ultimately, the defense allowed Alex Smith to finish 31/46, with 296 yards, a touchdown and no picks, while allowing too many conversions downfield.
