Jack Harbaugh is a fixture at Ravens practices, games and meetings, often speaking to the team or passing on his thoughts privately to coach John Harbaugh.
The retired former college football coach provided a winning example and wisdom to his sons, John Harbaugh and San Francisco 49ers coach Jim Harbaugh, winning a national championship at Western Kentucky.
Both of Jack Harbaugh's sons made it to the Super Bowl in February, a historic NFL clash of brothers won by the Ravens at the Mercedes-Benz Superdome.
With Father's Day today, John Harbaugh reflected on Jack Harbaugh and the holiday.
"There will be a call made, I'm sure, and he'll want to talk, which is fun," John Harbaugh said. "I'll have a lot of questions for him. And that will be the greatest Father's Day gift that probably I could give him or that I could get, either. I'll get a chance to spend time with my daughter, but I hope all the fathers out there cherish every second of it.
"It seems to me a little bit like a player, when you don't have something, you better not take it for granted. We only get our kids for a short span in this life, and there's nothing more precious and valuable than our kids. That relationship means everything to me, and I know it does to all of us standing around here that are dads."
Ultra-competitive to the core, John Harbaugh joked that he and his brother will be trying to beat each other for who gets on the phone first today with Jack Harbaugh.
"There's always a race," John Harbaugh said with a laugh. "Birthdays, there's always a competition of who can get to the phone call first. Believe me, my dad does keep track. He keeps track. I have East Coast ties, so it should be an advantage there."
