John Harbaugh appreciates Ravens' stability in turbulent NFL world

OWINGS MILLS, Md. -- The NFL has reached the halfway point in the season, and there has been plenty of change already due to the pressure to win now.

Gone are two head coaches (Miami's Joe Philbin and Tennessee's Ken Whisenhunt), two offensive coordinators (Detroit's Joe Lombardi and Indianapolis' Pep Hamilton) and one team president and general manager (Detroit's Tom Lewand and Martin Mayhew).

It's times like these that coach John Harbaugh appreciates the stability of a franchise like the Baltimore Ravens. In their 20th year of existence, the Ravens have had three head coaches (Ted Marchibroda, Brian Billick and Harbaugh), two presidents (David Modell and Dick Cass) and one general manager (Ozzie Newsome).

It helps that Harbaugh won a Super Bowl three years ago. But it also helps to have an owner like Steve Bisciotti, who gave Harbaugh an extension after the 2013 season, the first Harbaugh didn't lead Baltimore to the playoffs.

"I’m thankful every day for the opportunity to, first of all, breathe. And secondly, to coach, and to coach for the Baltimore Ravens," said Harbaugh, who is signed through the 2017 season. "It’s a tremendous franchise, has the best owner in the league, bar none -- Steve Bisciotti -- and best general manager [Ozzie Newsome] and the best team president [Dick Cass] and the best building. All those things combine to make a coach’s job something to be very grateful for. It’s just a great organization, and when I walk in the doors, I’m very grateful to be here.”

There could be changes with the Ravens' coaching staff after the season. That's what happens when a team underachieves. But there's no uncertainty surrounding Harbaugh.

Midway through his eighth season, Harbaugh is the seventh-longest tenured head coach in the NFL. Only New England's Bill Belichick (hired in 2000), Cincinnati's Marvin Lewis (2003), the New York Giants' Tom Coughlin (2004), Green Bay's Mike McCarthy (2006), New Orleans' Sean Payton (2006) and Pittsburgh's Mike Tomlin (2007) have been with their teams longer.

Since Harbaugh took over as the Ravens' coach in the 2008 season, there have been 54 head coaches fired in the NFL, including two this season. The Jacksonville Jaguars, who play the Ravens on Nov. 15, have had three head coaches (Jack Del Rio, Mike Mularkey, and Gus Bradley) and one interim one (Mel Tucker) since Harbaugh arrived in Baltimore.
