The San Francisco 49ers were flying high for most of their Week 1 matchup against the Detroit Lions. A fourth quarter score followed by a successful onside kick by Detroit quickly threatened San Francisco's once 28-point lead in the season opening matchup.
San Francisco's defense managed to hold off Detroit in the final :20 seconds of the game to maintain their lead and close out the day with a win.
Jeff Deeney of Pro Football Focus highlighted several 49ers who were key to the team's victory over the Lions. Here's a look at Sunday's top performers.
1. Trent Williams - 92.2 Overall Grade
Williams' 92.2 overall grade was not only the highest on the team, but also the highest of any NFL tackle so far in Week 1. The left tackle did not allow a single pressure in his 55-total snaps. Williams finished the day with a 75.7 pass-blocking grade and a 79.2 run-blocking grade.
2. Nick Bosa - 87.6 Overall Grade
In his first return to the field since Week 2 of the 2020 season, Bosa was back to form and earned the highest defensive grade on the 49ers. Bosa recorded five quarterback pressures (one sack, two hits, two hurries) as well as three run stops in 51 snaps on Sunday.
3. Deebo Samuel - 86.7 Overall Grade

Of his 189 yards, 109 came after the catch (12.1 average), 45 more than any other wide receiver on Sunday (Arizona Cardinals Rondale Moore - 64).
