Just months after Peyton Manning walked off the field a winner at Super Bowl 50, the 49ers are already holding a round of meetings with Bay Area officials about bringing the big game back to Santa Clara.

To persuade skeptics, they’ll be waving a new report on Super Bowl 50 that estimates the February extravaganza brought in $240 million for the Bay Area economy from out-of-town visitors.

The report by the private research outfit Sportsimpacts, commissioned by the Super Bowl 50 Host Committee and released Monday, says the average visitor spent $692 a day on food, lodging and entertainment.

“Everything we have heard from the NFL, as well as municipal and regional leaders throughout the Bay Area, reinforces our opinion that Super Bowl 50 was a major success in every critical area,” said 49ers President Al Guido. “We still have a lot of work to do on the planning over the next 18 to 24 months, but we are excited about the potential of bringing another Super Bowl to the Bay Area.”

The Sportsimpacts report says hotels were the biggest winners last time around, clocking in with $181.1 million in revenue during Super Bowl week. That’s more than four times the $41.6 million weekly average for midwinter.

Of course, it didn’t hurt that many hotels quadrupled their rates for that week.

The report didn’t include spending on Super Bowl-related events by locals who didn’t go to the game itself, the assumption being they would have spent that money elsewhere in the Bay Area had there been no Super Bowl.

The report also subtracted the expenses picked up by San Francisco and Santa Clara, including transportation and police costs.

Still, it’s unlikely to mollify critics in San Francisco, some of them on the Board of Supervisors, who blasted the expenditure of $9.6 million in city funds on what they called “a corporate party.”

“We have to learn the lesson that Santa Clara taught everyone,” said Supervisor Aaron Peskin. “If they want to come here and have a great party, then they can pay their way.”

The Sportsimpacts report says San Francisco, which invested the most in the event, got the biggest Super Bowl bang, taking in $137 million. That was followed by San Jose at $20 million, Santa Clara at $16 million and Oakland with $9 million, the report said.

If the 49ers do get the game back, it will be a while before kickoff at Levi’s Stadium. The next open spot on the NFL’s Super Bowl calendar is 2022.

Better call Saul: The four law firms that were first out the gate with a lawsuit over the sinking and tilting Millennium Tower might want to take a closer look at the homeowner they represent in their $500 million claim.

Not only does plaintiff John Jeffrey Eng no longer live in the condo high-rise at 301 Mission St., he hasn’t owned a place there since 2011 — years before there was any public disclosure that the building was sinking.

Eng, who was facing a bank foreclosure at the time, sold his 25th-floor unit “as is” to a cash buyer for $625,000, according to federal bankruptcy records on file in San Francisco.

Court records show that Eng has done business under 10 corporate names related to law, medicine, health, restaurants, finance and marketing. They also show that he was among the homeowners of the 595-unit Beacon condominium complex across from AT&T Park who sued its developers in 2006 over alleged construction defects and other issues. We’re told that case recently settled for $17 million.

Eng could not be reached for comment.

When we asked how Eng would show he suffered financially from the Millennium’s defects, Marc Corsi, a spokesman for the law firms that brought the case, said that was something the lawyers would have to argue in court.

The couple who bought Eng’s condo, Richard and Karen Kerbis, told us there was never a mention of the building sinking at the time of the sale.

“Quite honestly, if he knew there was a problem with the building, he should have disclosed it — and we should sue him,” Karen Kerbis said. She and her husband have since sold the unit.

Incidentally, on Friday, just days after we began asking Eng’s lawyers about their client, they filed an amended complaint to add a second plaintiff, Charlene Smith.

She still owns and occupies a condo in the 58-story building, they say.

Dream on: After sailing through the state Assembly in record time, a measure to legalize online fantasy sports sites as games of skill rather than chance has bogged down in the state Senate — where it may wind up sitting for another year.

In January, after intense lobbying from sports teams and TV networks, the Assembly overwhelmingly approved a bill aimed at legalizing daily fantasy sports sites such as DraftKings and FanDuel.

Once it went to the Senate, however, the bill became caught up in a fight over Internet poker — where gambling interests that want Online Hold’em legalized wondered why the sports games were going to the head of the line.

“We’re still optimistic that a strong consumer protection bill can be forged,” said FanDuel and DraftKings spokesman Steve Maviglio.

Maybe — but don’t bet on it happening this year.
