Pictures of Manning grace the walls at Circle City Tickets, a broker on the city's north side. Over the years, Manning has helped drive ticket sales, 6News' Tanya Spencer reported.

"The only thing I can maybe relate it to is IU basketball in Bloomington. A lot of people went because of Bobby Knight, because Knight was such a larger-than-life figure," said Mike Peduto, of Circle City Tickets. "I think Peyton's kind of in that same category."

Peduto said prices have dropped 20 percent with the uncertainty surrounding Manning, but he thinks prices can level out, as long as the team wins.

"I think a lot of it's going to depend on how the team looks in the first game this weekend," said Peduto.

At the Colts Pro Shop at Lucas Oil Stadium, No. 18 still reigns supreme. Manning merchandise is still as hot as ever, but a couple of fans have asked about Kerry Collins Colts jerseys. There is no word on when they might be there, but they are available online.

"Kerry Collins is a pretty good quarterback. I watched him throw a few passes, but he's not Peyton Manning. Peyton Manning is the man. He's the best quarterback in the NFL," said fan Marvin Murdock. "If he's not there, I'm nervous."

Murdock and season ticketholders Karen and Larry Burnett said they will go to the games regardless of Manning.

"We were season ticket holders when we were 1 and 13, so we love the winning, but we're used to the losing, too," Karen Burnett said.

All Colts fans and ticket brokers hope Manning is on the field as soon as possible. Brokers said the preseason began with a sales slump because of a looming lockout.

Peduto predicted that if Manning were out for the season and if the Colts are losing, resale values could drop up to 50 percent and the business could take a loss on season tickets already purchased.

"This year, we may have some sets we've bought that were marginal at the time, and now that we're selling them individually, we may not make it back," he said. "By the end of the year, I don't know what tickets will be going for."
