He need to utilize his amazing powerful slapshot more.
I actually kind of wish he wouldn't shoot quite as much . He's a bit one note in the offensive zone. He gets the puck, it's almost always ending up on net. I think he'll need to develop a bit more dynamic decision making if we want him to take the next step offensively and become a truly elite offensive guy.
Not that he needs to become an elite offensive player. He could change nothing and still put up ~40 points a year which is definitely very valuable.
