I'm totally on team Josi for the Hart. With 84 points already he's having one of the greatest seasons by dman in decades. He might get over 100 points which has been last time done by Brian Leetch in 91-92! Last time any dman even got to 90 points was in 93-94 by Ray Bourque, almost 30 years ago!
Currently he leads all dmen by 9 points (Makar with 75p) and leads all Nashville players by 12 points (Duchene 72p). And Josi doesn't only get power play points as he leads all dmen in even strength points with 51 (2nd Makar with 46), although he also leads league in PP points by dman and is 4th among all skaters.
If Josi can keep up this pace and get Nashville into the playoffs (really tough schedule for the remaining 13 games..), I would definitely vote for him to win the Hart.
Shesterkin has been great and would be in my second vote. Gaudreau, Huberdeau, Matthews and McDavid would round out my top 6. Aho, Kaprizov and Ovechkin would be in the next tier of choises.
