Ed Oliver still hasn’t forgotten about the critics who questioned the Buffalo Bills for overspending when they offered the defensive tackle a four-year, $68 million contract extension in June, nor the vow he made shortly after signing the deal. Three months into the season, the fifth-year player has solidified his role and validated his paycheck by nearly becoming an every-down player in anchoring Buffalo’s defensive front. Oliver leads Bills defensive linemen in having played 67% of this season’s snaps, and he's given the pass rush an added dimension with his ability to pressure the pocket from the middle.
