QB Josh Rosen, chosen with the No. 10 overall pick in the 2018 draft, might be available via trade — and it might not take a whole lot of resources to get him.

That's the takeaway from reading the situation with the Cardinals, who have the No. 1 overall pick in the 2019 draft and sound like they are smitten with QB Kyler Murray at that spot. Arizona took Rosen with the aforementioned No. 10 pick last year. But after just 13 starts, he might be the odd man out.

The price if they decide to trade him? Peter King surveyed a couple of sources who think all it would take to get Rosen is a third-round pick. Let's say it's accurate and the Cardinals are open for business.

Rosen is under contract for three more years at a reasonable cost. Worst-case scenario, he's at least a functional backup. Best-case scenario, maybe he fits into a team's long-term plans as he develops. A smart team will trade for him. Why not the Vikings?
