Rikard Gronborg, head coach of the Swedish national team agrees.
"Obviously, he's a tremendous hockey player. He's still young and learning his trade, right now, but he took some huge steps this year and has continued that here. He has been great for us," he explained. "Playing at this level is a real challenge for him physically, but he's still pretty young - his strength will come - and playing at a high level and getting that experience to really see where he needs to be is good for him. I think he's taken on that challenge and done real well with it so far."
Although known for his scoring, especially one heck of a onetimer from the circle on the power play, something he worked hard to perfect last summer, Pettersson said he considers himself more of a playmaker. Gronborg agrees.
"I don't think he's just a goal scorer. I see the vision he has on the ice and the passing skills he has and the awareness he has of where other players are at and I think that's separates him from just being a goalscorer," the coach explained. "I've also really appreciated the past couple weeks that I've worked with him that he works all over the ice. He does the back checking and all the dirty work as well and that really shows me a lot of his character. He has several layers to his game and, as a coach, that's something we like to see."
In five games at the world championship, Pettersson earned a goal and two assists before breaking his thumb in a preliminary round game against Switzerland. It will require surgery to repair and he is expected to miss 3-4 weeks, but it should not impact his summer training plans.
The fifth overall selection in last June's NHL Draft wants to focus on building strength, improving his agility in tight areas and continuing to work on his shot.
"Here, playing against NHL players, I am not strong enough and I lose the puck kind of easily and then I get frustrated," Pettersson explained. "I feel good that I'm able to play in this world championship and against NHL players and try my game at this level and see what I need to do and where I need to get better. I knew I had to bring my best game and make quick decisions and be smarter with the puck. I learned a lot in these games and it motivates me to train harder and become stronger and better."
As questions swirl about when he will make the jump to North America and try his hand at the NHL, Pettersson knows two things for sure.
