Rex Ryan had seen it many times before: The Baltimore Ravens didn't do much on offense, yet it hardly mattered because their defense was so sharp. That's how the Ravens won when Ryan was their defensive coordinator from 2005-08, and that is precisely the formula Baltimore used to beat Ryan's New York Jets on Sunday. Joe Flacco threw a 66-yard touchdown pass to Jacoby Jones, Justin Tucker kicked four field goals and the Ravens shut down the Jets' sputtering offense in a 19-3 victory. But Baltimore won on the strength of its defense. The unit forced three turnovers, limited the Jets to 220 yards and denied 11 of 12 third-down tries. "What can you say about our defense?" coach John Harbaugh said. It was a dominant defensive performance. It was the fewest points allowed by Baltimore since December 2009, a 48-3 win over Detroit. "I feel like we were dialed in today," linebacker Terrell Suggs said. There's always a little something added when we're playing Rex. We're proud of the fact what we didn't give up a touchdown, and getting off the field on third down was huge. Ryan, who also served as defensive line coach with Baltimore from 1999-2004, fell to 0-3 against his former team. "We knew, quite honestly, that their defense was going to be tough sledding," Ryan said. With that, we've got to be more efficient on third down. That's a big reason (for) the struggles. I thought we dropped too many balls, and that's where it started offensively. On defense, when you're playing in a game like that, you got to be sound, you got to be good and it has to be for 60 minutes. There's probably three or four plays that we weren't in. Over his last six games, Smith has thrown 10 interceptions and one touchdown pass. "This is not on one individual," Ryan said. This is on us, collectively. Obviously, that's the message Ryan conveyed to his players. "We got to back him up," offensive tackle Willie Colon said of Smith. We didn't do that today. But Smith's numbers have created conjecture that Ryan might be close to changing quarterbacks. "Everybody always wants a new quarterback in there," Smith said. I just keep trying to improve and work on myself. I know I can lead this team to the playoffs.
