For a while now, safety Kenny Vaccaro out of the University of Texas has been the top-rated safety on most boards. It just so happens that safety is a position of need for the Dallas Cowboys. Vaccaro revealed at the combine that the Cowboys have invited him for a visit to Valley Ranch. Vacccaro is generally rated to be a first-round talent, meaning that if the Cowboys really want him, they would almost certainly have use their 18th pick in the first round to get him if he's still available. While many think that defensive line is the position of need on defense, Stephen Jones had a different idea. "If there is a need on defense to me the biggest need is going to be safety," Jones said. "You got Church coming off an Achilles and obviously we really like everything we saw in Matt Johnson other than he couldn't get healthy."
