Williams is currently ranked as the No. 12 wide receiver available in this year's draft according to Scout.com.
As a senior, Williams was in a run-oriented offense, but still managed to catch 40 passes for 451 yards and three touchdowns. Sometimes used as a running back, Williams carried the rock 39 times for another 226 yards and three more touchdowns.
"I'm very versatile as a receiver," Williams told Scout.com in a recent interview. "I've got great hands, I run great routes, I can do a lot of things to help a team out."

"Williams is an explosive athlete who has tremendous ability anytime he has the ball," notes Scout.com NFL Draft Expert Chris Stueber. "He's quick off the line, reaches top speed instantly and has an outstanding burst in the open field. He has excellent body control and adjusts well to vertical throws.
"He's also a dynamic return specialist who has great vision and cut back ability that allows him to reach paydirt. He plays much faster than his timed speed."
The Cowboys are looking to add at least one wide receiver in this year's draft after releasing Terrell Owens earlier in March.
Roy Williams is first in line to be the new No. 1 receiver in the Cowboys' offense to replace Owens, however the team still needs to find additional weapons for QB Tony Romo.
