We’ll see how the 49ers divide responsibilities when Bartch is back at practice, which should be relatively soon. They also have veteran Matt Hennessy, who has posted strong run-blocking grades over his limited NFL action at left guard, and two rookie options for the position: seventh-round pick Connor Colby and undrafted signee Drew Moss. Like Hennessy, both of those players are strong run blockers, but they’ll have to polish their pass protection to enter the top of this conversation with Bartch and Zakelj.
