This was not an easy decision for Scott Frost.

After his UCF Knights clinched an AAC Championship and a perfect 12-0 season with a wild 62-55 win over Memphis in double overtime in Orlando, Frost sprinted over to his players and celebrated an incredible accomplishment. But when the UCF head coach was met by the cameras, his emotions overwhelmed him.

During the AAC title game, Brett McMurphy reported that Frost and Nebraska reached a seven-year, $35 million deal. It had been widely speculated that he would take the job, but nothing had been confirmed until Saturday afternoon. When he was asked about his future, Frost fought back tears.

“I’m going to go celebrate with my team,” he said.

Frost is expected to be introduced as Nebraska’s next head coach on Sunday, according to reports.

UCF was winless two seasons ago before Frost arrived in Orlando. Last year, he took the Knights bowling and finished the year 6-7. This year, UCF did the unthinkable and finished the year undefeated and conference champions. It’s also currently ranked No. 14 in the College Football Playoff rankings.

Frost is taking over a Nebraska program that finished the year 4-8 and suffered several blowout losses. Last Saturday, newly appointed athletic director Bill Moos fired Mike Riley, who went 19-19 in three seasons in Lincoln.

In two seasons at UCF, Frost is 18-7.
