Before the Kansas City Chiefs, there were the Philadelphia Eagles. And before Chiefs special teams coordinator Dave Toub, there was Baltimore Ravens head coach John Harbaugh.

Harbaugh served as special teams coordinator (1998-06) and secondary coach (2007) under Reid, who was the head coach of the Eagles from 1999-2012.

"I know firsthand that they're very well-coached and that they'll play hard," Reid said of the Ravens. "It's easy when you turn on the film to see they're not exactly what their record shows. They had a few injuries but the guys who are playing in there are playing their hearts out."

Of the nine seasons the two coached together, the Eagles made it to the playoffs in six, and they reached the Super Bowl in 2004.

Overall, Reid, with 130 wins and only three seasons with a record below .500, is the winningest coach in Philadelphia history.

Harbaugh was hired as special teams coordinator under former Philadelphia head coach Ray Rhodes and stayed on once the franchise hired Reid.

In 2007, Harbaugh became the secondary coach under legendary defensive mastermind and then-Eagles defensive coordinator Jim Johnson. Only a year later, he was hired to lead Baltimore, becoming the first coach in NFL history to advance to the playoffs in his first four seasons.

"I think he understood that I wanted to grow," Harbaugh said of Reid, "a great leader, a great boss is tuned in to the goals, aspirations, dreams of the people that he's leading. Andy is a great leader and he was always very respectful of those things, of me and of all his coaches."

Reid and Harbaugh are tied, 1-1, when facing each other as head coaches—a number fitting for two men who taught each other so much.

"You learn from a great coach like Andy and you certainly take all the great things that you learn and even let your personality shine," Harbaugh said. "Let it show and let it be something that you can be proud of."
