Strengths: Vaccaro is big and athletic, two qualities necessary to excel in Pittsburgh's scheme. He plays the run well and isn't afraid to make contact.
Vaccaro can play both safety positions, which would help give the Steelers depth and perhaps allow them to draft another safety in the later rounds.
Weaknesses: Vaccaro can be sloppy with his tackling, often times trying for the big hit rather than just making the tackle. He hasn't displayed a knack for interceptions, an area the Steelers desperately need to improve.
What to Watch at the Combine: Vaccaro needs to show fluid lateral movement during his time at the combine. If his times are a little slow, he may fall off the Steelers' radar.
Overall: If the Steelers plan on continuing with the zone blitz scheme after defensive coordinator Dick LeBeau retires, then Vaccaro would be a good fit. His athleticism and versatility would be perfect for the multiple packages the zone blitz utilizes.
However, if LeBeau's heir apparent, Keith Butler, and head coach Mike Tomlin decide to move toward a cover-2 scheme, Vaccaro may not be a good fit.
