Just speculation, but imagine this. I think you let Perry walk if you can sign Chandler Jones. He'd be double the price but we'd be set for the pass rush once another rookie is drafted. Rather than keeping Perry around and being hopeful he can replicate 2016, but uncertain about it. And then hoping Clay can get healthy stay healthy and replicate his better days, but again uncertain about it.
Jones Clay Fackrell Elliot and 2-3 round rookie.
This would prevent us from signing a top CB but Kirkpatrick Amukamara Claiborne or DRC if he is cut could probably be brought in. Then since the pass rush is set, you can probably draft a CB in the first round to pair with one of those Vets.
* Keep in mind I am not saying this should happen. Just drawing out the potential scenario if it did happen. It's interesting.
