Week 15 Projections
The Bills made Williams the NFL's highest-paid defensive player last year in the hopes that he would transform their pass rush, and while Williams ended the year with double-digit sacks his first year in Buffalo was considered a disappointment. The Bills are going to feature more 3-4 looks this year under new defensive coordinator Mike Pettine, but so long as Williams plays with his hand down enough to maintain DL eligibility, he should at least maintain low-end IDP DL1 value.
