IRVING, Texas -- While the early portions of the NFL draft went to offense, the defense has started to take over.

The Cowboys drafted William and Mary cornerback B.W. Webb in the fourth round on Saturday morning.

The Cowboys drafted offensive players with their first three picks before selecting safety J.J. Wilcox of Georgia Southern in the third round.

Webb was one of the 30 national visits the Cowboys conducted this month at Valley Ranch. Webb, 5-10, 184 pounds, is good in zone coverage and has the potential to play on the nickel and special teams.

In his first game at William and Mary, Webb picked off three passes against Virginia and returned one for a touchdown.
