OWINGS MILLS, Md. -- The Baltimore Ravens' win over the Miami Dolphins kept the team in the playoff hunt and John Harbaugh in an exclusive coaching club.

With the Ravens securing their eighth win Sunday, Harbaugh remains one of four coaches in NFL history to win a Super Bowl and not have a losing season. This elite list includes: Vince Lombardi, John Madden, Mike Tomlin and Harbaugh.

While there's a mutual respect with Tomlin, Harbaugh was awestruck when told that he shares an accomplishment with two Hall of Fame coaches in Lombardi and Madden.

"I can't believe it. That's amazing," Harbaugh said. "I've been blessed to get to know John Madden. We have a kind of relationship that he's mentoring a lot of us guys where I can call him up and talk to him anytime. Vince Lombardi is the icon of all our youth. Put it this way, there'd be no comparison question there. You can all safely say that."

In his seventh season, Harbaugh owns the fourth-best winning percentage (.648) among active NFL head coaches, compiling a 79-43 record. He is the only head coach in NFL history to win a playoff game in each of his first four and five seasons.

This season has been one of Harbaugh's best coaching jobs when you consider the amount of challenges the team has overcome. The Ravens (8-5) are a half-game out of first place in the AFC North despite the Ray Rice scandal, the suspension of Pro Bowl defensive tackle Haloti Ngata and eight starters (tight ends Dennis Pitta and Owen Daniels, offensive tackle Eugene Monroe, guard Kelechi Osemele, defensive end Chris Canty, cornerbacks Jimmy Smith, Lardarius Webb and Asa Jackson) missing at least one game to injury.

Harbaugh's strength is to never dwell on the past and constantly look forward. When Ngata was suspended last week, Harbaugh simply announced the news at the start of the team meeting before saying, "OK, let’s go to work.”

Quarterback Joe Flacco was asked about why the Ravens can handle adversity so well and he pointed immediately to Harbaugh.

"It starts with John and his attitude that he brings to the team meeting room ... and it filters throughout the rest of us," Flacco said. "So, we are able to keep that levelheadedness and keep the same mentality no matter what's happened the previous week."

Flacco said Harbaugh provides the guidance on how to handle difficulties.

"I think he’s so comfortable and so confident in what he is doing that he can portray that to all of us and we can [follow his lead]," Flacco said. "Let’s just say adversity is losing a game. We all don’t feel good coming in here on Tuesday after a loss. But when you see your head coach get up there and, while he is fiery, he is still confident about getting back to work and going out there the next week … I think he’s been doing a really good job with that, and that’s with everything.”
