Veteran offensive guard Chris Williams signed a four-year, $13.5 million deal with the Buffalo Bills.
Williams, a first-round pick (14th overall) out of Vanderbilt who was moved from tackle to guard and then released after four uneven seasons with the Chicago Bears, could unseat veteran Doug Legursky at left guard. He started 16 games with the St. Louis Rams at left guard last season.
Pro Football Focus graded Williams as the worst starter on the Rams’ offensive line last season.
Williams’ deal includes $5.5 million guaranteed. He played on a one-year, $1.4 million deal in 2013.
St. Louis also lost offensive tackle Rodger Saffold in free agency. Saffold signed a five-year, $42.5 million contract with the Oakland Raiders.
