With free agency entering the final stages, we'll review the Dallas Cowboys' past five free-agency classes.

We end the series with a look at 2013.

Players signed: Will Allen and Justin Durant

Starts earned: Eight

Analysis: Allen was signed as a veteran to improve the free safety position. The Cowboys had some younger players at those spots and Allen was supposed to bridge the gap. Yet, Allen started just two games and the team went with rookie J.J. Wilcox as the new starter. Allen was released in October and found a home with the Pittsburgh Steelers. After Allen, the Cowboys still couldn't find consistency in the free safety spot with Jeff Heath or Wilcox and they enter the 2014 season with uncertainty. Durant was also signed as a veteran linebacker in the 4-3 scheme. Durant started the season off strong with 13 tackles in the first three weeks of the season, but a groin injury suffered at San Diego cost him a game. Later, he injured a hamstring and was placed on injured reserve with two weeks to play in the regular season. Durant's replacement, much like the free safety position, involved a number of players.

Grade: C
