Williams, who turned 25 Friday, would have been a free agent after this season but the Bengals added four more years on a contract that keeps their starting safeties intact through the 2020 season.
On the first day of free agency back in March they inked George Iloka, 26, to a five-year, $30 million deal. They opted to go with the youth of Williams as Reggie Nelson, signed in Oakland last month off his first Pro Bowl appearance at age 32.
Although Williams, a third-round pick in 2013, has just four NFL starts, they’re encouraged with what he did while Iloka was injured last season and when Nelson left the play-off game early in the second quarter.
