The first thing that draws people to Williams is his size, as he is 6'5" and 200 pounds. His length is impressive, plus it seems like he is capable of adding more bulk to his frame.
On the perimeter, Williams routinely exhibits solid release quickness to get into his routes. He doesn't mind being pressed and jammed at the line since he has the strength to fight through cornerbacks attempting to disrupt his release.
Williams has enough lateral quickness and agility to wiggle around jams, and he shows good speed when getting downfield in his routes to stack himself on top of cornerbacks. He has light feet to cut at junctions, but his size and hands are his top assets.
The 5-star prospect knows how to shield defenders from the ball, and he has the length to pluck passes away from his frame. Williams also shows ideal adjust ability to balls, which proves he has a large catch radius. After the catch, Williams does have the ability to make plays as a runner.
His leaping ability, size, ball skills and ability to high-point balls should also make him a great weapon in the red zone.
