The Harbaugh family has played a big role in the Ravens coaching staffWell the Ravens have their man.  The team announced on Thursday afternoon that Don Martindale will be Baltimore’s new linebackers coach.  Martindale replaces Dean Pees who was promoted to defensive coordinator after Chuck Pagano left to coach the Colts.

We all should have known that Jack Del Rio wouldn’t reunite with the Ravens.  I cited “different eras” as my reasoning when first discussing candidates to replace Pagano.  Del Rio came from the Brian Billick era Ravens, a team and method that the front office and ownership have decided to put behind them.

Martindale comes to Baltimore with 18 years of coaching experience in both the NFL and at the college level.  Not surprisingly, he was on Jack Harbaugh’s coaching staff at Western Kentucky.

It seems that the Harbaugh family tree is becoming the Ravens index for coaching vacancies.

Here’s a fun little game.  Next time the Ravens need to replace a coach, just start looking at people near Jack, Jim or John.

Have these personal relationships held the Ravens back?  Look at Baltimore’s most controversial non-fire, Cam Cameron.  Despite Joe Flacco’s numbers declining in 2011, Cameron still hangs on as the Ravens offensive coordinator.  Did you know that Cameron was hired by John Harbaugh as an assistant 1997  at Indiana University?  Did you know that Cameron was the Jim Harbaugh’s quarterbacks coach at the University of Michigan?

Steve Bisciotti and Ozzie Newsome have put all their eggs in the Harbaugh basket.  Four straight trips to the postseason and two to the AFC championship are hard to argue against.    I just hope that when the Ravens have to make coaching changes, the decision is affected by these long relationships that have been established.
