Maybe he needed to develop a healthy fear of failure.
A lot of kids take their talent for granted until they see their dream slipping away.
He had a really tough time really once drafted.
Serious groin injury before his first NCAA season, was not healthy until ~February when season was close to done.
UND did not play anyone but Johnson until after Xmas in his 2nd year.
He did not play a SINGLE game between April 2015 and December 2016 as a result. And only 2x games with more than 20 minutes in net between April 2015 and September 2017.
His 2 games for North Dakota comprised of below 30 minutes total 12 minutes in relief and a first period where he allowed two.
Then his Dad died just as he went to the USHL.
Will be interesting to see what happens after this year. I guess now he will be a good Euro level goalie whatever and get a ~Czech/German/Swiss/Sweden/Finland chance down the line if does not come back to North America.
