Jets coach Rex Ryan is aware that the team's season opener against the Cowboys carries more weight because it will come on Sept. 11. "Usually, like I go against my brother and all that and you have a lot of fun with that, but I feel, I don't know it's different, like a responsibility," Ryan said. "And every week I have a responsibility to make sure our team is prepared but, I don't know, it just feels different to me. "The significance of it, it's stronger than any game I've ever felt. I feel more pressure on this game for whatever reason than any game I've ever coached it seems like." The Jets coach will be on the sideline opposite his twin brother Rob Ryan, the Dallas defensive coordinator.
