The Facts: Williams intends to sign with the Oakland Raiders, a source tells ESPN's Adam Schefter.

Diehards Line: Williams caught 41 passes for 653 yards and five touchdowns for the Chargers last year, and that 15.9-yard average would make him a big-play complement to newly-acquired Antonio Brown and veteran Jordy Nelson. The Raiders continue to add speed and talent on the outside -- both clear needs.
