By the end of Saturday night, either Cal quarterback Jared Goff or Arizona quarterback Anu Solomon will have four career wins.

Both lead undefeated teams into the first conference game of the season for either school. And in a conference silly with veteran quarterbacks, these two represent the future of the Pac-12 at the position.

In five combined games this season, they are completing 64.5 percent of their throws with 15 touchdowns to just two interceptions. Goff, a sophomore who started last season as a true freshman, has the Bears clicking to the tune of 43 points per game. Solomon, making just his fourth career start, headlines the No. 1 total offense in the league, which averages 582.7 yards per game.

There’s a reason the over/under for this game is in the 70s.

For Goff, Year No. 2 has been anything but a sophomore slump. Last season he army-crawled his way uphill through the muck and mess that was Cal’s 2013 season, picking up only one win but a lot of lessons along the way. In two games this year, he’s completing almost 68 percent of his passes -- up from 60.3 percent last season -- and he’s already guided the Bears to a road win over a Big Ten opponent.

Call it a sophomore surge.

“[Goff] is a year older and he looks even stronger. And the second year in the system is a big deal,” said Arizona coach Rich Rodriguez. “To play as a freshman as well as he did is remarkable. But now he’s kind of a seasoned veteran. He’s seeing the whole field and … playing with a lot of confidence. That’s for sure.”

For Solomon, this would be a pretty good start to his career -- having already earned wins over UNLV, UTSA and Nevada. Some might call that a sneaky tough schedule, especially for a guy with zero career snaps before this season.

Through the first three games of his career, Solomon is completing 62 percent of his throws with eight touchdowns and one interception. For comparison, through Goff’s first three career starts, he was completing 61 percent of his passes with seven touchdowns and four interceptions. Goff also had to face a ranked Northwestern team and No. 4 Ohio State in two of his first three games.

Still, Solomon has impressed coach Sonny Dykes, despite the limited body of work.

“They have played a couple of tight ballgames and it seems to me when the game gets tight, he plays better,” Dykes said. “When things tightened up against UTSA, he played well and I thought the same thing against Nevada. I think that’s a real sign of maturity and I think that’s impressive for a guy that’s only played in three ballgames.”

Against Arizona last season, Goff posted a career-high four touchdown passes in a narrow 33-28 loss. Or as Rodriguez describes it: “He threw it around pretty good on us last year.” Goff matched that number two weeks ago against Sacramento State and, according to Dykes, is playing with the confidence you’d expect from a guy with a year’s worth of experience.

“The biggest thing is last year he was still learning the plays,” Dykes said. “Now he’s run them all a couple hundred times. Everything happens faster. He sees things faster. He can anticipate better. The receivers are a year better. Everybody is on the same page, better than they were. The only way you have growth at the quarterback position is by playing and getting reps. He’s gotten a lot of reps.

“The more he plays, the better he’s going to get. We think he’s already pretty good. But we think he has a chance to be really good.”

Both teams boast outstanding receiving corps, which certainly helps out younger quarterbacks. That’s going to put a ton of pressure on the secondaries. Heading into this game, the Wildcats rank 10th in the conference in pass efficiency defense.

“Teams have attacked us through the air and had some success,” Rodriguez said. “Some people say that’s a secondary problem. No, it’s a total problem. Sometimes we aren’t getting a pass rush on and sometimes when you’re a little ahead teams will throw on you. But there’s no question we have to shore things up in a hurry because we’ve got some great throwing teams coming up. Including one coming in this weekend.”
