Dallas Cowboys

2015 Season

Jones was selected by the Dallas Cowboys in the first round (27th overall) of the 2015 NFL Draft. Although the Cowboys thought his best position was at free safety, his versatility and ability to learn different positions allowed the defense to use him in different packages and to deal with different player injuries. He played mainly at safety and slot corner, matching man-to-man against the opponents' biggest receivers.

Against the Miami Dolphins, his first start at right cornerback (in place of an injured Morris Claiborne) proved to be difficult. He gave up a 47-yard touchdown reception to Jarvis Landry, a 29-yard touchdown to Kenny Stills and left the field in the final minutes with an ankle injury. Against the Carolina Panthers in his second game as the starting cornerback, he performed better and had two key plays on the goal line to prevent a touchdown right before the end of the half. Against the Green Bay Packers, he had to finish the game at right cornerback, when Claiborne left with an injury.

In November, he passed J. J. Wilcox on the depth chart and was promoted as the starter at free safety. Against the New York Jets he started at cornerback in place of an injured Claiborne, but suffered a dislocated left knee after tackling wide receiver Quincy Enunwa, that he was able to pop back into place and continued to play a total of 71 snaps. He was beaten by Kenbrell Thompkins for a 43-yard gain that set up the winning field goal on the Jets' next-to-last drive. He finished the season with 11 starts (7 at safety), led the defense with 12 passes defensed and also played every down on special teams.
