Great news. Big downgrade in talent, bigger ice, missing a month of AHL for 6 or so games. Not worth it. The WJC is massively overrated for "development".
They want him to learn the game on small ice, so going to the WJC doesn't help, and he already experienced a win last year. You wanna learn how to be a pro, the WJC won't help you at all.
Also the player was consulted and agreed that not going was the right move.
