C Weston Richburg
A knee injury cut Richburg’s 2019 season short, and knee and quad injuries slowed him down during the 2018 campaign. However, Richburg is a difference maker for San Francisco when he’s on the field. He’s a very good pass blocker who was sorely missed during Super Bowl LIV. The 49ers have enough depth to survive without Richburg, but they’re at their best when he’s manning the middle. The only way he’s not the starter is if his knee injury lingers into the season.
