The coach actually is former Islander Olli Jokinen.
Räty was traided to Toronto's 6th round pick on #2020 draft, Axel Rindell. You could call Rindell still somewhat late bloomer, and his results in the Liiga are pretty solid so far, he was even on roster(did not play a single game tho) this spring on World Champs where Finland landed 2nd. So good price for Räty i would say, i'll guess Kärpät won this trade.
Jukurit is better team for Räty for sure than Kärpät, where Kärpät is best team in Liiga in 2000s, Jukurit is small expansion team without any succes whatsoever.
