The 10th overall pick in the 2005 NFL draft, Williams recorded 83 receptions for 987 receiving yards and three touchdowns with Seattle from 2010-2011.
At USC, the 6-foot-5 wide receiver notched 176 receptions for 2,579 receiving yards and 30 touchdowns in just two seasons. He set USC and Pac-10 records as a freshman in 2002 with 81 receptions, 1,265 receiving yards and 14 touchdowns.
