It happened to him 26 years ago, but Randall Cunningham still remembers what it felt like on game day as an NFL rookie replacing a 13-year veteran as the starting quarterback.
"I almost pooped myself," said Cunningham, who replaced Ron Jaworski as the Philadelphia Eagles' starting quarterback in Week 2 of the 1985 season.
"I was bright-eyed and bushy-tailed, a high draft pick [second round], and I could make things happen with my feet. But was I ready to start in the NFL? No way. I took eight cans of film home every night to watch. But so many things happened in that game that I wasn't used to in college."
Cunningham went 14-for-34 with four interceptions, no touchdowns and a 22.7 passer rating in a 17-6 loss to the Los Angeles Rams.
Sunday, the latest bright-eyed and bushy-tailed rookie will make his NFL starting debut when Vikings first-round draft pick Christian Ponder replaces another 13-year veteran, Donovan McNabb.
"Who are they playing?" Cunningham asked.
The Green Bay Packers.
"Talk about being thrown into the fire," said Cunningham, who also played for the Vikings. "Wow."
