They've got so many needs that they could use it anywhere. Even after the expected cuts, I don't think they have space for even a single Zeitler-like signing. If they do, that would be the biggest splash I expect. Beyond that they'll spread stuff as much as possible to cover as many of the gaps.
Bozeman is gone. Averett is gone. Elliot likely gone, he may be cheap enough to retain but I think they want a different answer at safety. I think they try to resign Ricard, but they may decide they don't have the space to blow $3-4M on a luxury item at FB. Houston probably gone.
I think they look for cheap deals with Campbell, Smith, and Bynes. I think Williams they probably let walk unless he comes really cheaply.
No idea on what FAs they'd pursue. But they need help at ever level of the defense and on the interior offensive line. Plus tackle if you're not willing to rely on Stanley returning.
In order of likelihood I think they cut Villanueva, Boykin, Young, Koch, and Ferguson. That would save a little over $17M (minus the ~$5M to fill out the roster afterwards). Restructure of Humphrey seems like a lock and that could create about $7M. Restructure of Stanley also feels likely, and that's about $6M. So those moves would generate close to $30M in space which could go a long ways towards fillings gaps.
