For Crist, it's an opportunity - his last - to show the NFL scouts what he can do. An opportunity he wants to seize.
"I think it's everyone's dream to ultimately play at the highest level, when playing any sport really," he said. "That's something that you can't make the main focus of what you're doing, but that's been a dream of mine since I was six years old. So I'm gonna do everything I can to hopefully make that a reality. But at the end of the day, I've always been a team guy. The team's always gonna come first to me."
His new team, and his old team. Crist obviously has his own responsibilities to take care of this fall, but he'll still be an interested observer in what happens here in the quarterback competition.
"All these guys that are playing this year are all some of my best friends," Crist said. "So I'm always very vested in how they're doing, and I want success for all those guys."
And as he prepares to say goodbye one more time, Crist has made peace with the way everything ended at Notre Dame.
"The thing is, Notre Dame did so much for me in the time that I was here that I'll always be grateful and always be indebted to Notre Dame," Crist said, "and what that degree entails, and just the relationships that I had here, the great people, the community.
"I mean, everything that went on in the four years that I was here, I'll always be thankful for and grateful for, and will always be a positive in my book."
A book he's still writing.
