Earler this season, back when the San Francisco 49ers were both trying to overcome a slew of serious injuries while also getting their offense into some sort of rhythm, it wasn't hard to pin a good deal of blame on the offensive line.
Specifically the interior, where a revolving door at left guard was only part of the issue alongside embattled center Jake Brendel and a seemingly regressing right guard Dominick Puni.
During the Niners' six-game win streak, however, the O-line has quietly gone from the offense's top liability into arguably one of head coach Kyle Shanahan's biggest strengths, and this unit is no longer viewed in the same critical light as it once was in the opening few weeks of the regular season.
