Not sure if its been mentioned, but Markstrom and his fiancee recently had a kid:

Not saying this is why he's had an off year, or that things will get any better with a newborn, but maybe this gets him out of his funk a little bit... I recall Tanev struggling a bit late last year with a newborn on the way.
P.S. Congrats Jacob!
