In a whirlwind few days, the Cardinals went from wrapping up their season, finishing football and business items to prepare for the offseason, to turning their stadium around to host a playoff game.

It started with a call from NFL executive Dawn Aponte, who asked Bidwill, "Could you be ready?"

State Farm Stadium often serves as the contingency plan in the event of an emergency, and by making that phone call, it was clear it was probable not possible. Even before the "Go" call from the league, Bidwill's organization spun into action.

"I spoke to the team later that morning and said, 'Look if this is gonna happen, let's get ahead of it,'" Bidwill said. "Let's get prepared and start thinking about everything that we'll need to be doing to make this happen."

From preparing the stadium to figuring out the ticket situation (Rams use Ticketmaster, Cardinals use SeatGeek) to going over logistics, they examined it all. Bidwill said he spoke to NFL Commissioner Roger Goodell several times to go over specifics.

"We shifted all of our attention even before the announcement to making sure that we were ready to go," Bidwill said. "We knew that the people in their organization have been going through tremendous stress, with their families and friends that were losing everything and we wanted to be as thoughtful as we could. And then we realized the families were coming. It was like, OK, that's a whole other layer to this."

Bidwill asked his staff to put together lists of everything the Rams could need, from activities to babysitters to ice cream parlors.

"We tried to think of everything," he said.

Above all else, it was the ticket sales that impressed Bidwill. Most neutral site games aren't like that. Pretty quickly, he realized this was not normal.

"It was pretty clear early within the first 12 minutes," he said. "It was like the pace of a Taylor Swift-type sale of a concert that was, it was really fast."

If the Rams win, they may head back to L.A., provided it's safe to do so. Bidwill said their doors remain open.
