The San Francisco 49ers aren't expecting fans of the Oakland Raiders to convert into supporters of their team.

The 49ers will be the lone franchise in the Bay Area for the third time in their history.

"The Raiders fans are a unique group," York said. "I don't know that they've necessarily been loyal to L.A. or to Oakland, I think they have always been loyal to the Raiders. I think you'll see the Raiders following them wherever they may go, and going to Las Vegas in a few years, I think you'll see that really take place.

"So for us, I don't think it's a big win for the 49ers, but I think it's a good thing for the National Football League. The Raiders have tried to get a deal done in Oakland for a decade-plus, and they were unfortunately unable to do anything, and I think Las Vegas put together a good opportunity for the Raiders to continue to have a good experience for their overall fan base wherever their fans come from."

Season-ticket revenue for the 49ers didn't spike when the Raiders left Oakland initially and didn't dip when they returned.
