Oakland Raiders general manager Mike Mayock continued his aggressiveness Wednesday, reportedly agreeing to a deal with wide receiver Tyrell Williams.

Williams is a big-bodied receiver who spent his first four years with the AFC West rival Chargers. At 6-foot-4, 205 pounds, Williams provides a big target for quarterback Derek Carr but also provides good speed.

Williams averages 16.3 yards per catch, which should help free up newly-acquired wide receiver Antonio Brown.

Williams entered the league as an undrafted free agent out of Western Oregon before hauling in 155 catches for 2,530 yard and 17 touchdowns over four years. His best season came in 2016, catching 69 receptions for 1,059 yards and seven touchdowns.

Williams joins Brown and veteran Jordy Nelson as the Raiders top wide receivers, who may be also losing TE Jared Cook to free agency.
