Fresno State only gets one more chance -- Saturday's Las Vegas Bowl against USC -- to lean on Derek Carr's right arm.
Next time those teams see each other, in the 2014 season opener, the offense will be in the hands of someone else's appendage.
That's a scary thought to Bulldogs fans, because there isn't an obvious heir apparent.
Not even coach Tim DeRuyter can tell you who Fresno State's starting quarterback will be Aug. 30 at the Coliseum.
"I don't know," DeRuyter said. "This spring that'll obviously be a big question."
It's something the Bulldogs already are asking themselves. During the first two bowl practices, backups Brian Burrell and Myles Carr each got a significant number of reps with the first-team offense. Freshman Zack Greenlee ran the scout team.
One of those three -- Burrell, Myles Carr (no relation to Derek) or Greenlee -- will be Fresno State's next starter.
"We plan on signing another quarterback, but it's highly doubtful that guy will come in and win the job," DeRuyter said. "The most realistic scenario is it's going to be one of those three."
The question is whom. It's complicated because Burrell, Myles Carr and Greenlee all possess different skills and are at different stages of development.
The Bulldogs will continue to run a no-huddle spread. But formations and play selection could look a lot different depending who is running it.
One thing is certain: Fresno State's 2014 offense won't be as wide-open and high-wire as the 2013 edition.
"If anybody thinks we're going to be able to do the same things next year, they're sorely mistaken," offensive coordinator Dave Schramm said.
"We will be productive, but there will be a lot less on the quarterback's plate going in. Just like there was a lot less on Derek's plate last year."
Let's take a closer look at the three candidates, starting with Burrell, the current No. 2.
A transfer from Bakersfield College, Burrell is a year younger, football-wise, than when he enrolled thanks to a successful NCAA appeal over a past injury. He now is a redshirt sophomore with two more seasons of eligibility.
Burrell is the biggest (6 feet, 4 inches and 219 pounds) of the three and has that year of experience at the JC level. He admits it was a rough transition.
"When I came here for my first practice I threw 20 passes and completed four or five," Burrell said. "Part of it was I was rattled, and part of it was I didn't know the routes perfectly and couldn't read the defense. But I'm a lot better now, to say the least."
Burrell showed enough to win the backup job and has seen mop-up duty in five games with the Bulldogs comfortably ahead. Just don't evaluate him on those outings.
"When I go in there it's a different mentality," Burrell said. "Usually we like to play fast. But when I'm in there it's slow it down and let's go home."
There's even less to go by on Myles Carr, a redshirt freshman from Arcadia High. The 6-1, 211-pounder is the best runner of the trio and probably has the strongest arm but needed time to master the playbook.
A Bulldogs offense with Carr Version 2.0 at the controls might look a lot like Oregon's: more run-based with shades of read and speed option.
"Most definitely -- I feel I fit in with that," Myles Carr said. "Having the ability to run really stresses defenses.
"I feel I'm getting more comfortable with the offense all the time."
Greenlee arrived with a fair amount of hype thanks to his lofty ranking at the 2012 Elite 11, a prestigious high school quarterback camp coached by Trent Dilfer.
The Lincoln-Stockton product has yet to appear in a game -- he is redshirting -- so team rules forbid him from speaking to nosy people like me.
Greenlee has impressed coaches with how he has picked up the offense and other nuances of the position. But at 6-1, 197, is more physical development needed before he is ready for an FBS-type pounding?
That's a question that can't be answered at present.
"I like where we're at," DeRuyter said. "We've got three guys that'll compete.
"Brian is a little ahead of the other two -- he's had more experience. Myles has gotten some snaps. He's got to do a better job taking care of the ball, but he's got ability. And then Zack's got a lot of talent but has to show it against live bullets."
Derek Carr's presence won't just be missed on Saturdays. On the practice field, during meetings, in the film room, the senior is a fount of knowledge. And more than willing to share.
One would hope Burrell, Myles Carr and Greenlee took advantage.
Derek Carr nods yes.
"They're always asking questions, and not basic questions like how to attack a certain coverage," he said. "They should already know those things.
"It's more like, 'When it's this coverage and this play, what do you do? What do you look at?' Something where you can tell their mind is really working."
Better ask now. Because next year, they'll have to provide their own answers.
