Coyotes need a center more than anything, so Cooley would be the logical pick at #3.
I see Seattle preferring Jiricek to Nemec, since size factored in a great deal in their 2021 draft day decision-making.
But there is a chance Jiricek could fall to the Flyers, if Seattle decided upon Nemec.
However, if the Devils took Jiricek, there would be no chance Slafkovsky would fall to #5 overall. Arizona would strongly consider him at #3, and there's no way he would fall past Seattle at #4.
So, you can put me on the record as saying there is a high chance the Flyers get Nemec, a decent chance they get Jiricek, and no conceivable way they get Slafkovsky.
