Williams dealt with plantar fasciitis in both feet last season, but he's believed to be healthy now, ESPN.com's Paul Gutierrez reports.
Williams technically missed only two games in the first season of a four-year, $44 million contract, but he didn't make much noise after Week 8. He scored five of his six touchdowns in his first five games, while his final nine appearances yielded only 344 yards and one score. In terms of per-target efficiency, he built on his excellent track record from his time with the Chargers, with his 10.2 YPT placing seventh among qualified pass catchers. Williams made a strong case to see more work if he can stay healthy, but the Raiders may have other ideas after using a first-round pick on Henry Ruggs and a third-round pick on Bryan Edwards. There's also a lot of touch competition coming from other positions, namely Josh Jacobs, Jalen Richard and Lynn Bowden in the backfield and Darren Waller and Jason Witten at tight end.
