EVANSTON-When Clayton Thorson trotted out to take the first rep with the first-team offense during Saturday's open practice, a murmur immediately rippled through the dozens of people assembled on the sideline at Ryan Field.

The question on their mind: Does this mean that Thorson has the upper hand in the three-way competition for the starting quarterback job with Matt Alviti and Zack Oliver? The three had been sharing snaps all spring, but just about everyone was wondering if the 6-foot-4 redshirt freshman had gained some sort of edge over his fellow QBs.

Head coach Pat Fitzgerald dumped a wet blanket on that theory immediately after the two-hour workout in front of a few hundred fans on a sunny, crisp and blustery morning.

"Today was his day to start first," he said simply. The three had switched off the lead role all spring, and that sequence will continue until the last practice, next Saturday.

In other words, the quarterback battle is still up for grabs, as are many of the other spots on Fitzgerald's injury-riddled team.

Fitzgerald wasn't about to disclose anything about the three-QB race that is the preoccupation of spring. On this Saturday, all three of them did some good things and some bad things, and no one separated himself from the pack.

"I think today was pretty similar to what we've seen all spring," he said. "We've seen great plays by the quarterbacks, and we've seen some missed reads and some mistakes. I think it's a work in progress, but I think all three are doing a good job."

His primary criterion for deciding on the winner remains a simple one: "The ability to run down the field and score points is going to be the ultimate deciding factor," he said.

On this day, then, Thorson was the one that met that standard. He hit running back Auston Anderson on a post pattern for a touchdown, the only true scoring drive of the afternoon. Thorson called that the highlight of his day.

"It felt good to get a score in there," he said. "You know if you get Auston Anderson in space, he's going to score a lot."

Fitzgerald likes that practices are closed to the media this year, if only to protect his three QBs from the daily scrutiny reporters would have generated.

"If I had practice open every day, you guys would over-analyze," he said.

The three players themselves didn't reveal much more than their head coach. They are not sure how much mobility will play a role in the battle, or whether a two-quarterback system could be a possibility. They all also talked about how close they are as friends.

"We help each other out," said Thorson. "I have a fun time with all these guys."

Thorson said he's focused less on winning the competition than he is trying to get the most out of every one of the one-third of the reps he is getting this spring. He didn't play a down last fall as a true freshman and spent most practices running the opponent's plays while leading the scout team offense.

While he is generally regarded as the best pure passer of the three, Thorson says he tries not to think in those terms.

"We can all run a little bit, and we can all throw the ball," he said.

Fitzgerald says that Alviti, who is regarded as the best runner of the trio, is finally letting the game come to him.

"If not anything else, he's overtrained, overworked (in the past)," said Fitzgerald. "That's a good problem, but if you do that, you can't just relax and play. He's starting to relay and play, and I think that shows confidence in the system."

Alviti agrees, citing the chemistry he built over the winter with running backs and quarterbacks.

"Coming up on my third year being here, I'm getting more comfortable with the system, getting better at the system, and knowing what I have to do," he said. "I'm slowing things down and taking a deep breath."

Oliver, the elder statesman of the bunch, seems the most relaxed of the three, at least in front of the media. He sneaked to the back of the media throng and asked Thorson a question about his touchdown pass. The fifth-year senior has, by far, the most experience, having thrown 61 passes in his career, 52 more than Alviti and 61 more than Thorson. Yet he wasn't really sure how much of an advantage that gives him over his peers.

"I'd like to think so, but I'm just coming in every day and working, just like everyone else."
