Shanahan to 'Consider' Nick Mullens as 49ers' Starter When C.J. Beathard Healthy

San Francisco 49ers head coach Kyle Shanahan said he'll "consider" keeping Nick Mullens as the Niners' starting quarterback after his three-touchdown performance in place of the injured C.J. Beathard in Thursday night's 34-3 blowout win over the Oakland Raiders. 

Matt Maiocco of NBC Sports Bay Area noted Shanahan wasn't prepared to announce any long-term plans immediately after the victory, though.

"Yeah, definitely we'll consider [making Mullens the starter]," he said. "Definitely not thinking about that right now, but our whole team played very well. Nick definitely did."

Mullens completed 16 of his 22 attempts for 262 yards with the three scores and no interceptions in an impressive first NFL start.

The win snapped the 49ers' six-game losing streak, including five since Beathard, who missed Thursday's contest because of wrist and thumb injuries, took the offensive reins after Jimmy Garoppolo suffered a season-ending torn ACL.

Shanahan didn't want to pin the recent issues entirely on Beathard, per Maiocco:

"I don't put all those struggles on just C.J. I think people make a huge mistake just saying, 'If you win, it's the quarterback. If you lose, it's the quarterback.' There are 11 guys on offense. There are 53 guys on our team. I thought our team had probably our best game of the year so far. That's nothing against C.J. I think C.J. would have played well tonight, too, if he played."

Beathard has connected on 60.4 percent of his throws with eight touchdowns and seven picks across six games in 2018. He didn't throw for three or more scores in any of his starts. Pro Football Focus grades him as the league's 26th-best quarterback.

It's too soon to tell whether Mullens, who went undrafted out of Southern Miss in 2017, could be the real deal or the Niners simply found lightning in a bottle against a bad Raiders team.

That said, Shanahan likely has little choice but to give Mullens another start when San Francisco takes on the New York Giants in Week 10, even if Beathard is healthy.
