The safety out of the University of Oklahoma and the rest of the draft choices will be with the Cowboys when they open camp Saturday.
"We are excited to have them," said Dallas Coach Dave Campo. "We certainly feel we had a good draft class and think we will have an opportunity to see it on the field."
All of the draft picks received seven-year contracts, although all have contracts that can be voided. Williams' contract cannot be voiced until after five seasons.
