Quarterback Joe Flacco’s 25-for-34, 236-yard, three-touchdown performance was a stark contrast from last year’s season opener, in which he completed only nine of 17 passes for 121 yards, one touchdown and one interception in a 20-0 shutout at the Cincinnati Bengals in his first showing since a back injury had kept him off the field for the entire preseason. But Flacco declined to compare how he felt Sunday against Buffalo. “I don’t like talking about my injuries, to be honest with you, too much,” he said. “You’re putting me in a little bit of a position to do it, but I feel good because we won the game, and that’s the most important part. I feel good because our team is out there feeling good about how we played today.” … The offense’s 6-for-6 showing in the red zone Sunday also featured success in converting third downs inside the Bills’ 20-yard line. On third-and-1 at the 11 on the unit’s opening drive of the game, Flacco dove 3 yards for the first down, and running back Alex Collins rumbled 8 yards for the touchdown on the ensuing play. Two possessions later, Flacco found running back Javorius Allen for an 11-yard gain on third-and-6 at the 19 and then connected with wide receiver John Brown on third-and-goal from the 7 for the score. “Those are the little things that we work on during the week,” wide receiver Willie Snead IV said. “Third-down conversions in the red zone, to be able to come out here and perform and put it all together gives us great confidence.” … A pair of former Ravens wide receivers in Kamar Aiken and Breshad Perriman reportedly took part in a workout Monday for the Philadelphia Eagles.
