Buffalo Bills defensive coordinator Mike Pettine knows Rex Ryan's defense. They worked alongside each other 11 years.
Pettine, however, claimed their long relationship will provide no edge Sunday against the New York Jets.
Pettine was the Jets' defensive coordinator the past four years and previously worked with Ryan on the Baltimore Ravens' defensive staff. Despite their familiarity, Pettine is wary of trying to guess what Ryan will do.
"The strength of the system that was built defensively is its flexibility, the ability do adapt each week to a particular opponent," Pettine said today at One Bills Drive. "Rex has 10 years' worth of material to draw from and tighten that down into a 30- or 40-call game plan, and it's just hard for me to even try.
"You're just chasing ghosts when you go, 'I might see this,' or, 'I might see this.' To me, it comes down to execution, and you've got to get your players lined up and play sound and hope that your guys can out-execute their guys on a given day."
Ryan, on a conference call with Bills reporters this afternoon, said neither he nor Pettine has an advantage given his familiarity with how the other thinks.
"You're still talking about hundreds of defenses that typically 40 or so are pulled for a game plan," Pettine said. "I mean, I know the mentality, but ... it's just too much volume to sit there and say, 'OK, I'm going to put myself in Rex's shoes, and here's what his game plan's going to be.' "
