The San Francisco 49ers secured a decisive victory over the Los Angeles Rams with a score of 27-7 in Week 1, providing answers to two critical questions about their defensive line and offensive interior. The 49ers demonstrated strong pass protection and effective run-blocking, particularly at left guard where Connor Colby played all snaps without yielding to pressure. This performance allowed the team to rack up 101 rushing yards between the tackles on 18 carries, marking a significant improvement in their offensive line's capabilities compared to pre-game concerns about personnel shortages and uncertainties.

Of course, they all lived up to that billing and more in the 27-7 Week 1 win over the Rams.

Not only was the 49ers’ pass rush able to put constant pressure on Matthew Stafford, it was another story for the Rams’ defensive front coming after Brock Purdy.

asserted
seven → put → duress
Of course, Trent Williams won his matchups with a less-than-100% Myles Garrett.

A lot of good individual plays, but just how they did as a group throughout the whole game was really impressive.
asserted
they → do → game
And they run-blocked very well too.
asserted
they → block → ?
If there’s one caveat, at least in the passing game, Shanahan’s screen-heavy scheme got the ball out of Purdy’s hands quickly and the Rams rarely rushed more than four.
asserted
Rams → ’ → four
But the undermanned Niners front seven didn’t need to blitz to break into the Rams’ backfield.
asserted
seven → need → backfield
In Raheem Morris’ debut as defensive coordinator, you could count on one hand the number of times the 49ers sent someone other than a defensive lineman after the passer: Three times by Fred Warner and once apiece by cornerbacks Upton Stout and Deommodore Lenoir.
uncertain
49ers → count → Stout
And yet, San Francisco was still able to hurry Rams quarterbacks seven times and hit them on seven other plays for 14 total pressures, already more than an eighth of the way to their total from last season, when they ranked third-from-the-bottom with a 16.7% pressure rate.
asserted
