During that span, Harbaugh has compiled a 67.7 winning percentage with an overall record of 63-30 that includes a 9-4 mark in the postseason.
When asked if he's consulting with other coaches that have won championships as far as how they attempted to defend their titles, Harbaugh indicated he'll continue to consult with his usual advisors.
That includes his father, former college football coach Jack Harbaugh, and members of the Ravens' organization like owner Steve Bisciotti, general manager Ozzie Newsome, assistant general manager Eric DeCosta, vice president of football administration Pat Moriarty, director of pro personnel Vince Newsome and the coaching staff.
"I talk to the people I usually talk to probably about what is going on," Harbaugh said as the Ravens concluded their offseason practice schedule last month. "You probably can figure out who those people are. No, it hasn't been too much different. Every year you face different challenges. This is new in a lot of different ways. You just try to do the best you can and make good choices and good decisions. We have a good team here. We have a lot of players that really care.
"We have a lot of leadership, young and veteran leadership. We have a great building from Steve Bisciotti right on through Ozzie, of course, Eric, Pat and Vince, and the coaching staff with our coordinators and our coaches always give us great input. It's a team effort. Really, truly it is a team effort in all those kinds of areas."
The Ravens have undergone significant turnover and have had to overhaul their roster with the retirements of middle linebacker Ray Lewis and center Matt Birk and free agent departures of free safety Ed Reed, inside linebacker Dannell Ellerbe, outside linebacker Paul Kruger and cornerback Cary Williams, trading wide receiver Anquan Boldin and cutting strong safety Bernard Pollard.
They've added inside linebackers Daryl Smith and Arthur Brown, center Gino Gradkowski, safeties Michael Huff and Matt Elam, outside linebacker Elvis Dumervil and defensive linemen Chris Canty and Marcus Spears.
And Harbaugh likes what he's seen this offseason in terms of the players' work ethic and philosophy toward starting from scratch and trying to build another winning team.
"Yes, that's exactly what it is," Harbaugh said. "Our guys understand that, and that's been their mindset as far as I can tell. They're looking forward to the opportunity to do something really special, just like every year. Just different this year."
