New Lions DT Sylvester Williams excited 'to build something' in Detroit Posted Apr 7, 2018 The Denver Broncos had one of the best run defenses in the NFL with Sylvester Williams starting at nose tackle three seasons ago. Now, the Detroit Lions are hoping Williams can have a similar impact on their defense. The Lions signed Williams to a one-year contract on Wednesday, adding a 313-pound run-stuffing presence to the middle of their defensive line. (Detroit Free Press)
