How to play this off-season with free agency?

[Walt White]

I don't know the cap space that well so people smarter will have to tell me what we can do. I'm just excited to see how good this team can get. All the building blocks are in place. It's a matter of how we can supplement the pieces. And I know retain the big pieces is most important.

So assuming we can keep Chris Jones and give Pat an extension, will we have any room at all in the cap to make impact additions? Keeping Sammy looks unlikely. Not sure how many of our corners we can keep?

Even if we play it perfect, will there be any cap left to add some vet free agents? It seems like a pretty strong offensive line class in free agency if we could add one or two. Or if we could add an LB (although Hitchens make a lot). Or a vet corner? Trade possibilities?

I'm just trying to get a realistic grid of what potential moves we can make. I know hitting on picks in the draft will be the biggest way to improve. But if we can get some discounted vets or something, that could go a long way into having freedom in drafting more luxury picks.
