One of the telling signs of maturity is how one deals with adversity, specifically when it’s admittedly self-inflicted. It was just over a year ago when a frustrated, 17-year-old Patrik Laine flipped Finland’s National Team coach Mika Marttila the bird during a game against the Czechs. He also reportedly issued him physical threats, thus leading to his expulsion from the 2014 Hlinka tournament after only three games.
