Adam Butler is known for being outspoken and he certainly was when he was asked about his feelings on the Raiders offensive line.

An eight-year pro, Butler had a breakout season for the Raiders last year. The former Vanderbilt standout recorded a career-high 65 tackles while posting five sacks for a second consecutive campaign. Butler was consistently one of the Raiders' best defensive lineman in a difficult season.

With the Raiders moving on from defensive tackle Christian Wilkins, many questions linger. Especially with the report that a teammate made a report to the team’s human resources department after Wilkins allegedly kissed him on the forehead.
