It kinda is Grönborgs job to say that Pettersson is not a lock to play. Sweden Hockey Games is the try-outs for all the non-NHLers. Of course Elias is a front runner for a spot.
Basically as of now, we have 9 NHL forwards that are guaranteed a spot:
Rikard Rakell
Mattias Janmark
Adrian Kempe
Gustav Nyquist
Mika Zibanejad
Mikael Backlund
Jacob de la Rose
Johan Larsson
Magnus Pääjärvi
Lias Andersson, Elias Pettersson and the rest of the forwards in Sweden Hockey Games are competing for the last spots. So that may be 4-5 open spots depending on how many forwards they bring to Denmark. And then we might a further NHLers that join, like Landeskog and Söderberg. Of course, I think Pettersson is good enough to grab one of the last spots
