Its an absolutely absurd discussion. There is no other way. Hallam knows this, he is nothing like the other coaches Sweden has had the misfortune of having the past 7 years.
The only possible way Leo is not the first center would be for Petterssons insurance thing to magically go away. While William Karlsson could be available after round 2 I don’t really see him as the kind of offensively dynamic player you want your first line center to be. Realisticly the only centers Sweden have that would trump Carlsson at all in that role is Pettersson, Zibanejad, Lindholm and Bäckström.
Andersson and Renberg know this aswell they probably just want something to talk about for the viewers.
