Walton Stromberg would benefit most from mental toughness off the ice. Walton has some bad habits - habits that he knows are bad, but simply can't stop. He's a chocoholic and also addicted to caffeine. Walton comes from Finland, which is one of the countries leading in consuming both coffee and chocolate, so it's kind of understandable. The dark place near the arctic circle has so little daylight during most of the year, that the regular caffeine and dopamine rushes are severely needed. But it would be better to have a life without addictions.

Another attribute Walton needs to improve is stickchecking. Walton keeps on grabbing the wrong stick from the hallway when he heads to ice from the locker room. Teammates constantly have to ask him to give their sticks back. He has to start checking that he takes the right stick, the one that has his name on it. It has become a running joke already, and his teammates sometimes spray his stick completely red so that it stands out enough for Walton to recognize it.
