Tony Romo had never seen anything like it.
The Cowboys quarterback noticed something a little different once Dallas started prepping for Sunday's season-opening matchup with the Jets, and it all can be attributed to one person: safety Andrew Sendejo.
The Jets claimed him off waivers from Dallas on Sunday, and don't think the Cowboys -- specifically Rob Ryan -- didn't take notice.
"It’s funny because Rob had a defense already put in for the Jets, a bunch of stuff in," Romo said this afternoon on a conference call. "Then when the Jets got Andrew Sendejo, he ended up switching a lot of that stuff up. So I thought that was pretty interesting when I was watching the defensive side of the ball here this week.
"I’ve never seen that before. So I think there’s a little cat-mouse game there for sure."
It'll probably be that same way for Romo with Rex Ryan and Mike Pettine calling the shots. But Romo thinks he's watched enough film to get a good read on last year's third-ranked defense.
"They are a great group," Romo said. "Obviously, they have great corners, a great coaching staff. They do a lot of different stuff. Communication will be different up there. We are going to have to communicate well. We are going to see a lot of Cover-2 man against them. They use a lot of two-highs safeties and play man-under coverage. They are going to throw some zone at us.
"So we have to account for these things and just be ready to go. I think it will be a great test for our ballclub and hopefully we’ll be up for it."
Romo, who's looking to bounce back from last year's season-ending broken collarbone suffered against the Giants on Oct. 25, certainly will.
"Aw man, it feels like it’s been forever since I played in a regular-season game," Romo said, "and I’m just excited to be playing and excited to go out there and continue to get better and improve, and just play football. I love the game, I love competing.
"It’s just going to be a great feeling."
