Free agent G/T Chris Williams is visiting the Bills Wednesday.
Williams started every game at left guard for the Rams last season, turning in a shaky performance at best. He'd still be a nice get for a team as a versatile backup. The o-line needy Rams reportedly remain interested as well

The St. Louis Post-Dispatch reports the Texans are interested in free agent G/T Chris Williams. Williams started all 16 games at left guard for the Rams last season, but was overmatched both as a pass protector and run blocker.
