Unless they’re planning to make significant roster cuts, free agency is all but over for the Atlanta Falcons.

On Tuesday Atlanta signed three free agents to address some of their holes on offense. First, they added former Indianapolis Colts guard Hugh Thornton, who may slide in to Chris Chester’s spot at right guard if he decides to hang up his cleats this offseason.

Next, the Falcons signed two fullbacks to compete for Patrick DiMarco’s old spot: Derrick Coleman, formerly of the Seattle Seahawks, and Soma Vainuku, who played college ball for incoming offensive coordinator Steve Sarkisian at USC.

While it’s nice to add more depth, there is now very little room left in the salary cap.

According to the latest public figures available by the NFLPA, the Falcons have just $2.2 million in cap space left over.

Atlanta still needs to find another edge rusher to pair with Vic Beasley. The team could also use more depth at safety, guard, defensive tackle and tight end. Since they have such little cap room to work with and still plan on extensions for top cornerback Desmond Trufant and MVP quarterback Matt Ryan, most likely coach Dan Quinn and general manager Thomas Dimitroff are planning to fill those needs in the upcoming NFL draft.
