The 49ers struggled on all fronts in their 26-15 loss to the Houston Texans and their PFF grades offer more detail on what went wrong.The defense was on the field for a whopping 80 plays, which likely added to their inability to stop Houston quarterback C.J. Stroud and the Texans’ offense. Stroud only was under pressure on 10 of his 42 dropbacks, even though 49ers defensive coordinator Robert Saleh dialed up the highest blitz rate of the season (33.3 percent).Stroud was very efficient when blitzed, completing 11 of his 13 attempts for 90 yards, a touchdown and a 121.2 passer rating.

When kept clean, Jones completed 16 of his 22 attempts for 137 yards, two touchdowns and a 118.9 passer rating. Here are more high and lowlights from the 49ers’ loss to the Texans:OFFENSEOffensive LineAllowed pressuresLT Trent Williams — one sack, one hit and two hurriesLG Connor Colby (20 pass blocking...
