Last week, the Cowboys met with 29 potential draft picks, one short of the league-mandated maximum of 30 players who can have pre-draft visits with teams.
Apparently the Cowboys were leaving that last spot open for Nebraska CB Prince Amukamara, who is at the Valley Ranch facility on Wednesday. Amukamara, widely considered the second-best CB prospect in this draft behind LSU's Patrick Peterson, has met with several scouts and coaches, including both secondary assistants – Dave Campo and Brett Maxie.
These pre-draft visits are not workouts, but more relaxed visits, designed for players to not only tour the facility but often sit down with coaches and look at film. It gives the player an idea what type of schemes each team will run and allows the coaches to see how players grasp different concepts they see on the film.
A few months ago, Amukamara was the majority pick for the Cowboys on many online mock drafts. Lately, he's slipped down a few picks as Tyron Smith and J.J. Watt have been selected more.
