Mullen comes from NFL bloodlines, which shows in his athletic ability and talent as a cover man. He was out of position as a perimeter cornerback and should fit in nicely with a move to the slot. He has quick feet and smooth hips to shade the route, but he needs to play with better discipline to prevent early hip commitment that receivers can use against him. Mullen is very tough as a run defender and takes excellent angles to the action on the move. His lack of length could hurt him in the draft, but he has the talent to play the pro game.
Williams lacks the length and explosiveness of an outside corner but displayed his play strength and toughness at that position in the Big Ten. Williams has decent mirror-and-match footwork from press but can be a little late to accelerate quickly when forced to flip and chase. He plays with good recognition from zone and is quick to dart in on throws. His physical/athletic profile does not stand out and the lack of takeaways over the last two seasons could hurt him.
