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.
The reason this would never work is because the Vikings would have 24hrs to skim through Murray tape and make this move. Cousins was the franchise QB up until a little over 24hrs ago. Maybe they had been preparing for the off-season and were looking at Murray as a potential future guy. But the vast majority of the film you would want to see is ahead of us, how he plays for the Cards post injury, and outside of Kliffs wack ass air raid. You don’t shell out your entire future for an unknown. Murray is a good QB and if the cardinals are drafting Caleb Williams or Maye or whomever you know damn well Minnesota would do their due diligence this off-season and it could be a viable move for a seemingly win-now team (Darrisaw, Jefferson, Bynum, later years of Smith and Hunter, etc). But 24hrs to make this decision is ridiculous and would never happen from a Vikings perspective. And that’s not even starting on the Cardinals perspective where a new regime clearly wants a fresh evaluation on their signed franchise guy.
