"It was definitely a wake-up call," said Boise State linebacker Blake Renaud. "We are realizing what it takes to be a winning Division I football team."
"We've got to get better," he said.
But this is still Boise State, the winningest football program in the country since 2000.
"Teams can have great seasons with two losses, one loss," Renaud said. "It's time to grow up."
Wide receiver Geraldo Boldewijn, who had eight catches in the season opener, said practices have been energetic this week.
"There's a lot of stuff to fix, but I think we'll start off with a lot of energy and stay positive," he said. "I think we'll bounce back.
Boise State (0-1) was ranked No. 19 in the preseason poll but fell out after suffering its biggest loss since a 48-13 drubbing by Georgia in 2005.
Boise State coach Chris Petersen is taking the long view when it comes to last week's loss. The Broncos typically schedule a tough opponent to open the season, he said.
"You open up every year like we open up, you're going to get your nose bloodied," Petersen said. "It's just a matter of time."
