Wilcox is mostly a hard-hitting box safety who works best as a part-time player. He played in just over 50% of the defensive snaps for the Dallas Cowboys last year, after losing his starting job the year before.
The Bucs re-signed Chris Conte just before the start of free agency and still have Keith Tandy on the roster, three safeties who probably each work best in a rotation, though Tandy is most likely to get a full-time starting job. The Bucs are likely to add a fourth safety in the 2017 NFL draft, which features a very deep group of safeties. Even with Conte and Wilcox in the building I wouldn't be surprised if they take a safety in the first round.
Wilcox is the Bucs' third external free agent signing after DeSean Jackson and Chris Baker.
