Kaprizov has reached such a high skill level that I legitimately can't tell if people are being serious or joking when they say things like this, anymore.
I think looking at his 47 from last year with a really slow start, and the very fast start from this year, has a lot of people (me included) thinking that 50 should be attainable.
Looking at his games 14-81 from last year, he had 44 in 68 games. This year he needs 40 in 69 games.
Obviously there's a lot of time left and his cold streak could come at another time of the season, but with 10 in 13 games, he has a pretty good start.
I know I won't actually be upset/mad/trade Kaprizov if he falls just short again, but mildly disappointed is a pretty apt term, given we all really want him to do it, and there's a reasonable chance he could.
