At 5-foot-9 and 180 pounds, Antoine Winfield doesn't have the imposing size of fellow cornerbacks Richard Sherman and Brandon Browner, his new teammates with the Seahawks.
"He may be the most physical corner in the league, and that includes Sherman and Browner," Williamson told "Bob and Groz" on Tuesday. "He's a hitter, he plays the run exceptionally well, the closer you get him to the ball the better he is."
Winfield's deal, still unofficial, is reportedly for one year. With the Seahawks set on the outside with Sherman and Browner, Winfield seems like a logical replacement for Marcus Trufant, who struggled at times last season while serving as Seattle's primary nickel corner.
That's where Williamson thinks the 35-year-old Winfield is best suited to play at this stage of his career.
"He has good short-area quickness but not elite speed anymore, so you don't want him running down the sidelines with A.J. Green so much as you'd rather him do battle with the Wes Welkers and the slot receivers and blitz ..., have him attack the running game," he said.
