At this point, after what Kempe showed in one game, what Pettersson struggled to do in several, I would push up Kempe or Hörnqvist to the second line. Kempe showed NHL skill in the same way Janmark has done it. He skated with strength, skill and purpose.
I'd rather see what Hörnqvist/ Kempe can do in an offensive line, than watch Pettersson getting owned yet another game 5 v5, being knocked down by some unanimous defenseman from league X all game long.
Pettersson's physical strength isn't bad, it's abysmal. He's very interesting on the PP, but 5 on 5 he's been a liability so far, if you want your team to keep the puck.
That's why I think Pettersson going over to NA leagues next season is a joke. So he has nothing to prove in SEL? Go to KHL for a year then and get some strength, because I have no clue what value he could bring to an NHL team at this moment. So he is very skilled and very smart? So what, when anybody can push him away from the puck at this level?
"But Kempe did it against Austria!" Yeah, well, Pettersson was being owned by Belarusian, Czech and to some lesser extent French defensemen, is that much of a defense speech?
