Too often in 2017, the Buffalo Bills were gashed right up the middle in the run game. The responsibility for that gashing is up for debate, as it could either be the fault of the defensive tackles or the linebackers they are supposed to free up to make plays, but it is abundantly clear that both positions were in desperate need of upgrades this offseason.
The Bills did that, replacing the traded Marcell Dareus with another big-name free agent, re-signing a team legend, and adding a stud prospect in the middle rounds of the 2018 NFL Draft to overhaul the depth chart.
