Aaron Jones and David Bahktiari have big cap numbers next year because of all the restructuring. My guess is they will trade/release Bahktiari and gain cap relief, but lose a very good LT. I think they'll keep Jones.
They also need to sign Gary to a long term contract, and 5th year option Jordan Love.
They will definitely have cap space to operate, but I wouldn't expect a big spending spree. It only looks like they have more cap space than they actually will.
