No. 4: 49ers Center Alex Mack

For the first two weeks of the season, the 49ers offensive line looked like an entirely different unit than the one that was patchworked together for the bulk of 2020.

In Week 3, though, the storyline was entirely different. It was Green Bay that dominated the line of scrimmage, and not the Niners.

A big reason why centers around veteran center Alex Mack, who easily had his worst game of his brief career with San Francisco, finishing the bout with a rough 55.5 overall grade and two pressures and a sack allowed, according to Pro Football Focus.

Mack might not be the perennial Pro Bowl-caliber player he once was earlier in his career. Yet he’s still a significant upgrade over any option the 49ers tried out there last season.

Much like the Packers, the Seahawks aren’t exactly known for a prolific pass rush. Yet Green Bay’s pass rush, even along the interior, was able to do its job well enough last Sunday. In order for this issue to not repeat itself, Mack will have to provide more of his reputable self instead of being underperforming and underdelivering like he was a week ago.
