Trey Lance shaky in 49ers preseason Week 1 loss vs. Raiders

Statistically, Trey Lance looked OK in the 49ers' preseason bout versus the Raiders. But the numbers didn't tell the whole story.

Perhaps the Las Vegas Raiders truly wanted to win Sunday's preseason bout against the San Francisco 49ers, and they acted like it with some dominant efforts over the first half that got them out to a 14-7 lead by halftime, and things didn't necessarily improve for Lance's teammates by the time the 34-7 exhibition defeat was final.

But few will worry too much about Raiders running back Zamir White punching big holes in the center of the Niners' B-team defensive line.

No, the focus will be on quarterback Trey Lance.

With San Francisco's starters not playing in the exhibition bout, No. 1 quarterback Brock Purdy got to take the day off, while Lance played every offensive snap in the first half before giving way to fellow quarterback Sam Darnold after halftime.

The stat sheet suggests Lance had himself a decent outing, but that's not what the game film will necessarily reveal.

Trey Lance tosses a TD that should have been one of 2 interceptions thrown

Lance's final line after being relieved at halftime was 10-of-15 for 112 yards, a touchdown and a passer rating of 111.0, although his offensive line didn't do him too many favors and influenced at least two of the four sacks Lance took during his time on the field.

There were moments of decisiveness, yes. And while there is some understanding that Lance could be a bit rusty, seeing his first game-like time since breaking his ankle in Week 2 last year, one would have liked to see more from Lance than just a handful of impressive throws.

Case in point, two of Lance's tosses should have been easy interceptions by Las Vegas, including the touchdown grab by tight end Ross Dwelley that was more luck than skill:

If there's any glaring conclusion, it's that Lance desperately needs more reps to both make up for his lack of experience in college and the fact he has just four regular-season starts at the NFL level over the last two years.

49ers B-team offensive line shaky in preseason debut

Aside from veteran lineman Jon Feliciano, most of San Francisco's reserves on its offensive line lack a good deal of experience, and it showed on Sunday.

In particular, second-year lineman Nick Zakelj both gave up numerous pressures and was flagged multiple times for holding calls while getting field time at right guard.

If the 49ers' O-line stays healthy, this isn't a concern.

If the Niners suffer a moderate deal of injury attrition up front, though, it could be.

Jake Moody misses his first and second (exhibition) field-goal tries

San Francisco used a third-round NFL Draft pick on Michigan kicker Jake Moody, the highest specialist drafted last spring.

He missed his first field-goal try in an NFL game setting, albeit an exhibition one, from 40 yards out. And then he missed another from 58 yards out, wide and to the right.

Make of that what you will.

The 49ers will be at home for Week 2 of the NFL preseason when they'll take on the Denver Broncos at Levi's Stadium on Sunday, Aug. 20.
