Wilkins went undrafted this year out of South Florida and is gaining his first opportunity with an NFL team. The Buccaneers brought him in for a workout during their rookie minicamp in May, so they were clearly impressed enough to sign him.
During his college career, Wilkins recorded 109 total tackles, two tackles for loss, 0.5 sack, 19 pass defenses, and three interceptions.
