Roman Josi and the Edmonton Oilers?

There's no link connecting the Edmonton Oilers to defensman Roman Josi, but it sounds like there are some people trying to make one. 

Daily Faceoff Edmonton dropped a video of them discussing a comment by NHL insider David Pagnotta that there some quiet chatter in Nashville that the Predators might (and might be a very loose term) consider trading Josi. 

Given that he's got just one more season on his deal after this one, could the 36-year-old be on the move if the Predators determine he won't help them in their window to win? 

What would the Oilers have to pay to get the $9 million defenseman out of Nashville?
