Will the saints try to sign any more free agents?

We can afford several vets if we designate Harper as a June 1st cut. It would free up around 5 million off of this years cap. Plus with the new CBA we can do it at any time, do not have to wait till June 1st. The facts are he does not fit the defense we will be running. How many sacks did the cowboys safeties have the last couple of years? It's not a Greg Williams defense, the safeties have to be able to cover and make plays. That's why we drafted a safety that can do that. We can use the extra cap room to improve our team with vet free agents, to help resign Jimmy Graham, or roll over to next year since we are already over next years cap.
