I agree that he should be in the conversation. As Johnnybegood13 noted, going by the definition of the Hart trophy it's tough to find another player who is more valuable to his team. Kaprizov is leading the Wild in scoring, close to 20pts ahead of the teams next highest scorer. Great thread and completely agree he's getting overlooked in discussions.
For how good Matthews is there's Marner - McDavid has Draisaitl, Huberdeau has Barkov et al. Gaudreau etc.
Not to take anything away from the absolute monster MVP caliber seasons we're seeing from the players listed above, but for me they split votes. If the trophy is awarded to the player adjudged to be the most valuable to his team, hard to look past Kaprizov.
I think Evason has a chance at Jack Adams but that will be another interesting race. It's between him and Sutter for me.
