To be fair, a top prospect was attached to Datsyuk. Chychrun was the incentive to take the dead cap.
I like Fillpula, I'm just honestly not sure what value he has with that contract. Not seeing the incentive to take him at full price.
They did swap picks though. It's not like Detroit sent the #16 outright. It was #16 for #20 and #53, which in an of itself isn't all that unheard of. Chychrun is the best prospect in the deal, but before it happened people were acting like Detroit was going to have to offer Mantha or Svechnikov just to get sombody to pick up the phone.
It only ever takes one team in 29 to be willing to take on a bad contract.
