"I'd be out of a job for two minutes," Ryan said Thursday. "I mean, who are we kidding? I'm not worried about it. Love the Raiders (but) if that happens, so be it. I'd be out of a job for two minutes."
The Raiders had the NFL's third-ranked defense in 2006 and were No. 1 against the pass. But Oakland has struggled this season, blowing numerous fourth-quarter leads while allowing 100-yard rushers in 10 of its 15 games so far.
Heading into Sunday's game against playoff-bound San Diego, the Raiders are 26th in total defense and 31st against the run. With each passing loss, there has been more focus on the job that Ryan is doing. And with Kiffin's father, Monte, expected to be looking for work in the offseason after his contract in Tampa Bay runs out, speculation has been that the Raiders would be willing to let Ryan go and replace him with the elder Kiffin.
Lane Kiffin, however, said Thursday that he has yet to determine what he'll do in terms of the coaching staff.
"I'm continuing to evaluate everything and look at everything and make us as good as we can be," Kiffin said. "We'll make those decisions on a number of things but no decisions have been made at all on any of those things.
"It has been disappointing to return 11 starters. We definitely felt that the defense was going to be the strength of our team this season, coming off of last season and hoping that we'd improve into this season. But it all goes together. There's been a number of times that the offense has not helped the defense and put the defense right back on the field, and the special teams has not won the field-position battles in a number of games. So, our record has shown what we've done as a team and not on one side of the ball at all. So, we're 4-11 as a team, and we need to get better."
Ryan, who took over as Oakland's defensive coordinator in 2004 after coaching linebackers for New England, said he has not spoken to Kiffin or anyone in the Raiders' organization about his job security.
"I haven't talked to anybody about it," Ryan said. "I've coached my ass off. I mean, (the media) bring it up every day so you can speculate on it. I don't care."
