STANFORD -- Stanford absolutely, positively does not have a quarterback controversy -- at least not yet.
Josh Nunes will remain the starter Saturday when the Cardinal visits Colorado, but backup Kevin Hogan's role will expand -- and it might continue expanding if the mobile redshirt freshman runs the option effectively.
"We'll see how it goes the rest of the year," Stanford coach David Shaw said Tuesday. "Kevin has played so well with what we've given him to do that we can't not give him more.
"There are things Josh has done well that we're pleased with and things Josh has not done well that we're not pleased with. This is what's prudent."
Nunes, who won the job in training camp, directed Stanford to come-from-behind victories over USC and Arizona. But he ranks eighth in the conference in passing efficiency with a 120.0 rating and has completed just 52.6 percent of his passes. In a narrow victory over Washington State last week, he was 7 of 15 for 136 yards.
"We need to be more efficient in the passing game," Shaw said. "It's partially the quarterback, it's partially not the quarterback. ...
"We're going to give Kevin a bit more time, but at same time we're also going to play Josh. We'll let that play out. Each guy has their things that we are packaging together that will hopefully make us a more efficient offense.
"(Hogan) is not ready to take it all right now, and I'm not ready to take it all away from Josh."
Shaw estimated that Hogan would take 12 to 20 snaps in Boulder. While he is comfortable running the spread option, Hogan might throw from the pocket, as well.
Asked if he was concerned about the potential impact of Hogan's expanded role on Nunes' confidence, Shaw said:
"Not as all. As I said in front of the team, this is big-time college football. There's competition everywhere. Josh has responded great in practice, and so has Kevin. It's not necessarily to compete to be the starter. It's competing for plays."
Nunes responded matter-of-factly when asked Tuesday about Hogan.
"He has done a lot of good things on the field," Nunes said. "If it helps get a 'W,' I'm all for it."
Reserve Brett Nottingham is "still getting his share of reps in," Shaw said.
