Milton Williams is a big man with a big contract, and he has big plans for the New England Patriots defense. The Patriots introduced the defensive lineman to New England on Thursday, as the team welcomed in four of its signings from the first week of NFL free agency.

He’s a journeyman run stuffer, now on his fourth team in five years. Tonga is expected to back up fellow free-agent addition Milton Williams and Christian Barmore (pending Barmore’s recovery from blood clots). Even though his playing time may be limited, the 28-year-old said Friday he’s excited to join a talented duo.

Williams hits pay dirt with reportedly a Patriots record-setting contract agreement after coming up big in the Super Bowl for the Eagles.
