Sign of times: Ravens hang piece of football philosophy from goalposts

OWINGS MILLS, Md. -- When the Baltimore Ravens took the field this offseason, they were met with a piece of football philosophy from a close friend of the Harbaugh family.

The white sign hanging from a goalpost on the outside fields, as well as one in the indoor facility, reads:

The uncommitted player

The out-of-shape player

The absent-minded player

and the bad player

all look alike

The inspiration for the message comes from Dave Adolph, a great friend of coach John Harbaugh's father, Jack. Adolph was also the defensive coordinator for Jim Harbaugh at the University of San Diego from 2004 to 2006, before joining him as a data analyst at Michigan in 2015.

Adolph died in February at the age of 79.

"Coach Adolph was a big part of our family and our football philosophy, and Jim especially embraced it," John Harbaugh said.

Harbaugh has used signage around the team facility to instill messages since he was hired in Baltimore in 2008.

One sign inside the team meeting room reads: "W.I.N." -- What's Important Now -- which is a phrased coined by Lou Holtz. Another one inside the facility is "The Team, The Team, The Team," which comes from a famous speech by Bo Schembechler.

Harbaugh's latest sign carries the same ideology, although it's not an exact quote.

"It is a little bit tweaked for the NFL, I have to be honest," Harbaugh said. "It was a little bit more edgy, probably. But it is pretty edgy and we like it. I think it is a great message for players to get every day when they walk underneath the upright."
