I'm still not sure how I feel about this contract for Nashville. It's somewhere between "not very good", and "will be 5 years of Brent Seabrook on the back end".
He puts up a ton of even strength points but is generally regarded as bad defensively. A lot of the advanced statistical models aren't very high on him. I think they generally underestimate the value of elite offensive defensemen, although a lot of that is due to underrating their PP value where Josi has historically been good other than last season when the Preds PP was just a complete disaster. It's well within reasonable aging curves that he'll be unplayable towards the end of this deal (he'll be 38 when it ends), but it's basically market value and he's their captain
