The San Francisco 49ers have been busy upgrading the defensive front with pass rushers capable of getting to the quarterback. They also got a linebacker in Kwon Alexander to help take the edge off. Without a doubt the pass rushing department got a shot in the arm, but how about the run defense? The 49ers were middle-of the road in 2018 in terms of numbers, a steady improvement since the atrocious showing in 2016 under Jim O’Neil.
Well, Pro Football Focus may think differently. They are doing their rankings of run defenders and rank the 49ers run defense last in the league.
