Former Saints defensive coordinator Rob Ryan hasn’t been asked much about his firing in New Orleans during two hours on the NFL Network Sunday morning.

For the most part, the NFL Network has hinted at his departure, rather than address it directly.

But Ryan did comment on his firing after Marshall Faulk brought up the subject on Sunday morning.

“Everything in New Orleans is being blamed on me, including Katrina. I think that’s a little far-fetched,” Ryan said. “The bottom line is this: I’ll hold my head high and walk out in the sunset, but believe me, I’ll come back with a vengeance.”

Ryan acknowledged the Saints needed to make a move to turn around a defense that is dead last in the NFL in both scoring and total yardage, 30th in the league against the run and on pace to set an NFL record for the worst opposing passer rating ever.

“Something had to be done,” Ryan said. “Right now, the defense is ranked 33rd in the league, and there’s only 32 teams. I had a lot to do with it.”
