The question ASU football fans have been asking since Saturday still doesn’t have answer.

Coach Dennis Erickson said he has not made up his mind as to who will start at quarterback when the Sun Devils (4-5, 2-4 Pac-10) hit the road to counter No. 14 Oregon (7-2, 5-1) on Saturday.

“I haven’t made a decision on what I’m going to do yet,” Erickson told the media at his weekly press conference on Monday. “There are things you’ve got to think about going in [to Oregon]. We are going to make that decision probably in the couple days. We’re going to wait and see what transpires in practice.”

After senior quarterback Danny Sullivan threw two interceptions in the first half against USC, including one that was returned 55 yards for a touchdown, Erickson started the second half with freshman Brock Osweiler under center.

Osweiler led the Sun Devils on their only touchdown drive of the game — an 80-yard march that ended in a 23-yard touchdown pass to senior wide receiver Chris McGaha — but also struggled, at times, to hit his receivers, finishing 11-of-27 passing for 153 yards and an interception that came on a Hail Mary heave to end the game.

After reviewing film of the 14-9 loss to USC, Erickson said Sullivan “didn’t play as bad as everybody might have thought.”

“It’s not that [Sullivan] went out there and played so bad that you’ve got to yank him,” the coach said. “I made the change because I wanted to get some energy on offense, which Brock brought to us. He threw the football, got a touchdown, made some plays, and it was exciting for people to watch. However, there were times during that game where his inexperience came out, too.”

Sullivan finished the first half 12-of-23 for 113 yards and the two interceptions.

Erickson said the atmosphere of this week’s venue, Autzen Stadium, which is widely regarded as one of the rowdiest places to play in the nation, could factor in to his choice of starter.

“That has an effect, because it is a hard place to play,” Erickson said. “It’s an experience for anyone to play in there.”

Quiet impact

Senior linebacker Gerald Munns is quietly having a productive season for the ASU defense.

Munns, who lost his starting job to vaunted freshman Vontaze Burfict a few weeks into the season, came up with several key fourth-quarter tackles against the Trojans, including one for a loss.

“He's played very well all year,” Erickson said. “He doesn't get a lot of credit because Vontaze is a guy out there who makes a lot of plays and is flamboyant and all that.”

Blount is back

After landing the “punch heard around the world” on Boise State defensive end Byron Hout on the opening night of the college football season back in September, Oregon suspended senior running back LaGarrette Blount for the rest of the season.

But on Monday, the Pac-10 approved a request for reinstatement submitted by the school, allowing Blount, who missed eight games, to rejoin No. 14 Oregon when it hosts ASU on Saturday.

“I’m happy for him, I really am,” Erickson said. “I don't obviously know the whole situation, but I do know that he seems like a good kid who made a mistake, and I think they're handling it the right way.”

In a statement released Monday, Blount said he is glad to have the opportunity to amend his actions.

“Now it is up to me to prove to people that their lasting impressions of me are not what they saw in Boise,” he said.

The game between the Ducks and the Sun Devils will be televised on ESPN beginning at 8:20 p.m. Arizona time.
