PITTSBURGH (AP) — Pittsburgh Steelers coach Mike Tomlin isn’t dwelling on “what-ifs” after his team edged Baltimore to win the AFC North title for the first time in five years. While Tomlin is aware Pittsburgh’s margin of error is razor thin, he’s not going to apologize after the Steelers reached the playoffs when Baltimore’s Tyler Loop missed a 44-yard field-goal attempt on the final play. The Steelers face the streaking Houston Texans in the first round. Oddsmakers have made Houston an early favorite. Pittsburgh quarterback Aaron Rodgers is optimistic, saying the thrilling victory over Ravens should give the Steelers an added confidence boost.
