While the 49ers signing of center Alex Mack didn’t fly under the radar, his presence could reap huge rewards for quarterback Jimmy Garoppolo in 2021.

The relationship between San Francisco 49ers quarterback Jimmy Garoppolo and newly acquired center Alex Mack should be one fans pay closer attention to in 2021.

It’s a form of chemistry Garoppolo didn’t have last season. Or late in 2019 and into the playoffs that season either. In the wake of former starting center Weston Richburg’s serious knee injury, which ultimately led to him retiring just over a year and a half later, the Niners have been forced to employ a revolving door at the position, both with and without Garoppolo in the lineup.
