Martavis Bryant had a sparkling debut, but the shine was tarnished some as defenses gathered film to study his moves and tendencies. On Sunday, the Steelers rookie receiver proved that even film study isn't an equalizer for speed. Bryant sprinted by cornerback Adam Jones to score on a 94-yard pass from quarterback Ben Roethlisberger midway through the fourth quarter to cement a 42-21 victory over the Cincinnati Bengals at Paul Brown Stadium. Bryant's long-distance catch and carry capped a day in which the offense torched the Bengals defense with an array of big plays to help the Steelers (8-5) narrow their deficit in the AFC North to a half-game behind Cincinnati (8-4-1). “We felt we could get outside on them because they like to peek inside,” said Bryant, who had an 80-yard touchdown catch against the New York Jets in Week 10. “It was a great throw by Ben and great protection by the offensive line. It was the call right from the start, and we just executed it perfectly.” Bryant's score was one of two big plays that ignited the offense. Running back Le'Veon Bell ripped off a 53-yard run on the first play of the fourth quarter after Bengals receiver A.J. Green scored on an 81-yard pass from Andy Dalton on the final play of the third. Bell's jaunt along the left sideline set up a Shaun Suisham 44-yard field goal that trimmed the deficit to 21-20.
