Rex Ryan to Buffalo Bills -- does that impact Giants' defensive coordinator search?

The New York Giants' search for a defensive coordinator got a lot more interesting over the past 24 hours. The big coaching news of the day is that ex-New York Jets coach Rex Ryan is now head coach of the Buffalo Bills. You can head over to Buffalo Rumblings to see how Bills fans react to that news.

The hiring of Ryan is Buffalo could mean the end of Jim Schwartz' tenure as defensive coordinator there. Ralph Vacchiano of the Daily News has reported that the Giants are interested in talking to Schwartz, former head coach of the Detroit Lions.

Vic Carucci, Bills beat writer for The Buffalo News, is reporting that the Bills want to keep Schwartz.

The #Bills have "every intention" of keeping DC Jim Schwartz, just told by high-ranking team source.

The Giants, of course, are already set to interview Buffalo defensive line coach Pepper Johnson for the vacant defensive coordinator job. That interview is expected to take place on Monday.

Steve Spagnuolo, the former Giants defensive coordinator who is considered a leading candidate for a return engagement, is also now available for an interview since the Baltimore Ravens lost to the New England Patriots in the AFC Divisional Round on Saturday. Spagnuolo is the Ravens defensive backs coach.

Also Saturday, legendary Pittsburgh Steelers defensive coordinator Dick LeBeau stepped down from that job. The 77-year-old insisted he is not retiring. LeBeau to the Giants seems extremely unlikely, but we'll drop his name here and acknowledge that at least some Giants fans have thought about it.
