ORCHARD PARK, N.Y. — Rex Ryan is holding himself answerable for the Bills' slow start. At the same time, he made a significant change to his coaching staff by firing offensive coordinator Greg Roman on Friday. Roman was let go in a bid to kick-start the Bills' sputtering Tyrod Taylor-led attack. "I'm accountable for everything that goes on here," Ryan said. "And I'm accountable for making decisions like this. It falls on me. And I accept those responsibilities." The Bills announced the move a day after they fell to 0-2 with a 37-31 loss to the Jets. Running backs coach Anthony Lynn will take over as coordinator. Lynn also serves as an assistant head coach and has spent the past eight years working under Ryan. Roman was in his second season as coordinator. Ryan wouldn't say what specific changes he hoped to see from the offense. But he indicated that getting the ball to the Bills' top playmakers would be a priority. The offense is off to a sputtering start. It had just 160 yards — Buffalo's lowest total in a decade — in a season-opening 13-7 loss at Baltimore on Sunday. Against the Jets, the Bills had 307 yards of offense, with more than half coming on two plays: Taylor's 84-yard touchdown pass to Marquise Goodwin and a 74-yard touchdown pass to Greg Salas. Buffalo had 16 first downs, had one drive reach the red zone and converted 3 of 10 third-down chances. Fines roundup: Steelers receiver Antonio Brown was fined $21,000 by the NFL, $12,000 for a celebratory touchdown dance in a win against the Redskins on Monday and $9,000 for wearing baby blue shoes. Brown said there is a message behind the shoes, but he wouldn't divulge what it is. … Rams defensive tackle Aaron Donald was fined $21,269 for his actions that led to his ejection against the 49ers on Monday. His penalties included making contact with an official. … Panthers guard Trai Turner was fined $9,115 for taunting the Broncos' Chris Harris Jr. in the Panthers' opening loss last week.
