Here's what ESPN's St. Louis Rams reporter Nick Wagoner wrote about Williams last month:
While Williams was reliable, left guard remains a position that could definitely use an upgrade. Williams had some good moments as a run blocker but for the most part struggled against bigger, more physical fronts in the NFC West.
When the Rams traveled to San Francisco, Arizona and Seattle late in the season, Williams had some extremely rough outings, particularly against the Cardinals.
For what it’s worth, Pro Football Focus graded Williams at minus-21.8, the worst grade of any player on the team.
If nothing else, bringing Williams back figures to be a relatively cheap option to fill a possible hole on the offensive line. He played on a one-year, $1.376 million contract with incentives in 2013 and a similar deal might make sense if the Rams choose to bring him back.
Should the Rams lose Saffold, bringing Williams might make even more sense given his ability to play guard and tackle. Beyond Williams, the Rams also have guard Brandon Washington, a player they still have hopes for and whom they carried on the roster most of the season. Shelley Smith is another option, though he too is an unrestricted free agent.
In an ideal world, Williams is probably best suited as a utility backup capable of playing anywhere on the line and backing up at four positions. But if the Rams intend to improve the offensive line in 2014, improving at left guard is a necessity.
The Bills are also hosting free-agent cornerback Nolan Carroll on Wednesday.
