The details here actually don’t really matter outside of Danielle Hunter being involved. This actually makes sense considering Jonathan Gannon’s familiarity with Hunter.
So, let’s assume the trade looks something like this:
Vikings give Danielle Hunter + a conditional 2nd
Cardinals give Kyler Murray + a conditional 4th
Kylers Cap hit for 2024 is 16m.
The Vikings currently have 7m in cap room.
Trading Hunter would create another 11m in cap room, leaving the Vikings with 18m in space, just enough to fit Kylers contract for 2024.
The Cardinals have about 11m in cap room, and would pick up around 8m of Hunters cap hit for 2024, leaving them with ~2m in cap room after the trade.
As crazy as this idea seems on the nose, it is actually super plausible if the Vikings determine Kyler is their guy past this season.
