SEATTLE (AP) — Najee Harris rushed for a season-high 122 yards and bullied his way into the end zone for a pair of touchdowns, and the Pittsburgh Steelers kept their playoff hopes alive into Week 18 with a 30-23 win over the Seattle Seahawks. Using a punishing running attack that faced little resistance from Seattle, the Steelers pushed their way into the final week of the regular season with a chance at the postseason and ensured that Mike Tomlin’s team would yet again avoid a losing record. Pittsburgh thrived against Seattle’s run defense that has been awful for more than half the season and finished with 202 yards rushing and a season-high 468 total yards.
