The Cleveland Browns have been destroyed in the run game most of the season. The team seemed to prioritize speed and pass game needs over size and run game needs at defensive tackle and linebacker the last few offseasons.
With limited answers up the middle, teams that had struggled to run the ball all season (Los Angeles Chargers, Miami Dolphins) and teams with backup running backs carrying most of the load (Atlanta Falcons, Baltimore Ravens) ran all over the place on the way to victories.
GM Andrew Berry has not seemed to value run-stuffing defenders up the middle with DT Andrew Billings the last, failed, attempt at finding one.
