One of the 49ers’ fiercest rivals may have helped shape the Warriors’ dynasty.

OK, that might be an overstatement, but on a podcast that debuted Monday, Steve Kerr and Seahawks coach Pete Carroll discussed how Kerr visited Carroll and his team as he was preparing to take over the Warriors in 2014.

The simple fact that Kerr observed and visited with Carroll has been well reported. Butt on the duo’s first episode of “Flying Coach”, a podcast from The Ringer to help the coaches bide their time during the coronavirus crisis and raise money for relief efforts, they discussed what advice Carroll gave and how Kerr has used it in the years since.

A name familiar to 49ers fans came up: Bill Walsh.

Carroll, a San Francisco native and childhood 49ers fan, never coached under Walsh, but the father of the 49ers’ dynasty was around the team as an advisor when Carroll was San Francisco’s defensive coordinator in 1995-96. The now-rival coach used the opportunity to learn from a master of the craft.

The younger coach, fresh off a failed season leading the New York Jets, picked Walsh’s brain about building the 49ers’ dynasty.

“I had a chance to ask him about all of ‘How did you do it? Why did you do this? What was your thinking here? Why this play or why this coach?’” Carroll said. “And even talking through their cycles of their time together with Joe [Montana], Jerry [Rice], all those guys and Steve Young coming up, we talked through all that stuff. It was fun anyway, whether it had to do with coaching or not, it helped me.”

But the bigger lesson he gained, and later dispensed on Kerr as he prepped to be a first-time NBA head coach, was about having a vision.

“You called me into your office, probably on the third day, we sat down and you go ‘How are you going to coach your team?’ Kerr said. “I go, ‘So, like, what offense are you going to run?’ and you go ‘No, no, that stuff doesn’t matter.’ I’m like ‘Jeez, I just spent like two years trying to design my offense and Pete Carroll told me none of that stuff matters.’”

Carroll and Kerr agreed that the culture of a team is the most important thing when it comes to success, even though they came to that conclusion through different paths.

Carroll learned the hard way, through failures with the Jets and Patriots, ultimately finding success at USC and with the Seahawks. Kerr credited Phil Jackson and Gregg Popovich with instilling portions of that in him while playing — and winning championships — with the Bulls and Spurs.

“Everything that the players feel when they walk into the gym or onto the field every day that they come to the facility, it has to be real. And the values that are important to you as a coach have to come alive. That’s how culture is defined.”

Kerr’s test may have come last year as the Warriors’ locker room suffered turbulence and eventually Kevin Durant left in free agency.

The coronavirus crisis may completely erase the Warriors’ down year from playoff record books if the postseason is canceled, and Kerr will have the chance with a healthy team to re-establish that positive culture.

Kerr specifically mentioned joy as a major principal in the Warriors organization, spurred on by his time playing.

“That’s one of our team values with the warriors, is joy. I just always felt like as a player, that was when I played my best, when I was having the most fun,” he said. “I happened to inherit maybe the most joyful basketball player in NBA history in Steph Curry. In culture, obviously, your values are important, but the connection with key players is so important, as well.”
