With 20 players set to be restricted or unrestricted free agents, the Dallas Cowboys will have plenty of decisions to make on whom to keep and whom to let go.

Let’s take a look at the free agents to be and how they could fit into the Cowboys' future:

Defensive end Anthony Spencer

Type: Unrestricted

What he did: He missed the first three games as he worked his way back from microfracture surgery that limited him to one game in 2013. The coaches credited him with 25 tackles, a half sack, one tackle for loss, 17 quarterback pressures, one pass deflection, a forced fumble and fumble recovery in 13 games.

What he could do: As the season wore on and the more confident Spencer became in his knee, the better he played. Is he a 16-game starter these days? Perhaps not, but as the Cowboys look to rebuild their defensive line he would be a good piece for a year or two. Although he has outside linebacker experience in a 3-4 scheme, the knee injury might force him to remain as a 4-3 defensive end, which helps the Cowboys. He is Jason Garrett's kind of guy: He will do his work, do what is asked and not complain.

What it should cost: He made $1.25 million in base salary and had roster bonuses of $46,875 per game as he worked his way back. Since he has not recorded a full sack since 2012 and teams will be concerned about the knee, he is looking at a similar make-good contract as he enters his ninth season.
