Whenever the 49ers and their vaunted defense are mentioned, the discussion almost always starts with Nick Bosa, Fred Warner, or even Talanoa Hufanga as of late. But what often gets overlooked is the massive impact that the big fellas on the interior of the defensive line have had on the 49ers' defense, being an elite unit for the fourth consecutive year.
They may not possess the same flash that the edge rushers or the stars in the secondary do, but make no mistake about it; the work being done in the trenches is just as important to the success of this defense as the contributions from any other position group.
