Funny how five months and no games can radically change the vibe of a franchise. The 49ers, after a three-season tailspin, evoked optimism Wednesday night at a “State of the Franchise” event that attracted some 1,000 fans to the Santa Clara Convention Center.

It started with CEO Jed York drawing tempered applause, a nod to his latest overhaul. Standing ovations soon followed for the new regime of general manager John Lynch and coach Kyle Shanahan. Ultimately stealing the two-hour show were veterans-turned-comics Joe Staley and NaVorro Bowman – “The Joe and Bo Show,” as it were.

Here is what we learned from — and at times laughed about – in a fan-outreach event last held in 2010, amid the ill-fated Mike Singletary era:

— Stadium signage: Levi’s Stadium finally will show off the 49ers’ storied tradition. Retired jersey numbers and other historical elements will be displayed atop the west-side suite tower. Posters from victorious Super Bowls will spruce up the concourse. Perhaps that will help spark a missing, home-field advantage; the 49ers are 9-15 there since its 2014 opening.

— Bowman revealed that Staley won the 49ers’ offseason program’s best athlete award. “Joe exceeded in every single conditioning test that we had,” Bowman said. “The guy is unbelievable.”

Staley’s response: “Where’s this going, because you’re never nice to me?” Then Staley shared a “fun” story how he accidentally punched Bowman in the face earlier Wednesday. How come? Because after Bowman playfully slugged a cardboard cutout of Staley in the training room recognizing the offseason award, Staley said he countered with a “fake” punch before Bowman “leaned into it … and I got real scared.”

— Staley on the 49ers’ new vibe: “This is my sixth head coach (in 11 years).” The crowd groaned. Staley continued: “Yeah. Um. But there definitely is a different feel with a new coach coming in.” He cited a heightened sense of attention to detail and urgency, adding that players have come in with “excitedness – that’s not a word – and real vigor.”

— York on his annual upheaval: “First and foremost we haven’t been where we want to be,” York began. “It’s never easy to make changes. You don’t like to be an organization that has change. A big piece of that was you had guys that weren’t necessarily part of the 49ers fabric to begin with.” York then noted how Shanahan’s father, Mike, coached the 49ers (offensive coordinator 1992-94) and how Lynch played at Stanford under Bill Walsh, so this new regime “understands what the 49ers mean.”

— Season-ticket sales are being renewed on a “staggering” 97.3-percent basis over the past three years, according to president Al Guido. One wise-cracking fan in Wednesday’s audience shouted how he thought that number represented the amount of seats without shade at Levi’s Stadium.

— The 49ers hope that proposed, mixed-use developments nearby will enhance their bid this October to host Super Bowls 57 and 58. Guido thanked fans and the community for their support in hosting Super Bowl 50 last year.

— Home-game themes: Franchise icon Dwight Clark, who’s battling ALS, will be honored Oct. 22 against the Dallas Cowboys in a game also recognizing cancer awareness. Tom Rathman will be ushered into the 49ers Hall of Fame in conjunction with the Sept. 10 season opener against Carolina. Season-ticket holder giveaways will be part of each game.

— Paraag Marathe, the 49ers salary cap expert and chief strategy officer, said they’ve signed a league-high 25 free agents this year, as opposed to 23 over the previous four years combined. “First and foremost for us, we spend every single dollar of the salary cap. There will not be a dollar unspent,” Marathe said. “… We still, over the next two years, have the most cap room in the NFL. We have $22 million more than the No. 2 team and $60 million more than the average. We’re set up to be flexible to get more players or sign or own players in the future.”

— Linebacker Reuben Foster, one of four rookies introduced, is so fabulously charismatic he should already have his own radio show. Foster got baited into showing his “chicken dance” celebration for his first pending touchdown return. Said Foster: “The thing that surprised me was how big NaVorro Bowman’s arms are. His arms are like my legs. It’s crazy.”

— Shanahan on Lynch: “Being around John day in and day out now, he’s the exact same as the first time I spent five minutes with him. That’s what’s been most impressive. You know what you’re getting the first time you meet a guy. He’s that way every day. The biggest surprise is I didn’t know he is Captain America in real life.”

— Lynch on Shanahan: “I knew the offensive mind that I thought was really special and ahead of the curve. But what I’ve been so impressed is watching him in front of the team, the way guys respond to him, the way he stimulates them by teaching them, by educating them and by having fun.”

— Shanahan’s first-year plan: “My goal when we get out there this year is that every Sunday, our team, our fans, our organization believes we’re going to win that game. Whether that happens or not, we believe we’re going to do it because we put the work in, we’re prepared and we can live with the consequences.”

— Among the questions submitted by fans was one, from John Shepard of Roseville, challenging Shanahan to name his three favorite Drake songs. Shanahan’s response: “I mean what album do you want to talk about?” The 37-year-old coach’s favorites: “One Dance,” “Started From The Bottom” and “Free Smoke.”

— Defensive coordinator Robert Saleh on what he wants opponents to think of the 49ers: “I want them to see our style on tape. If they’re thinking about our violence on Wednesday, we feel we’ve already won the game.”

— Special teams coordinator Richard Hightower said his favorite things about the Bay Area are the family-friendly options, such as the beach, the mountains and the malls. “My least favorite thing: Can anyone say, ‘Cost of living?’ ”

— Quarterback Brian Hoyer and wide receiver Pierre Garcon said all the right things about their free agency courting, tracing their decisions to having previously played under Shanahan.

— Shanahan on the offseason program: “It’s been exciting to get the guys out there. They’re going hard. We’ve got a good group of guys, good people.”
