This is a bit of an unconventional trade. The motivation for the Canes is they clear the rest of Kotkaniemi's deal, which allows them to re-sign Jarvis, Teravainen, Necas, Drury, and Skjei who are all expiring. They don't lose much the rest of the season because Liljegren can slide right in with Skjei, or drop down and Orlov can move over to the right side. Plus they swap out Kotkaniemi, who is currently listed as their 4C, for 2 guys who can move around in their top 9. For the Leafs, Kotkaniemi with a change of scenery and with his skill set, is likely a big upgrade as the Leafs 3C, or he can take on the center role on the Tavares line and allow the Leafs to move Tavares to the wing. Pesce is an obvious fit with Rielly on the Leafs top pair.

The Canes probably wouldn't go for it, but if they are going to pick one of Pesce or Skjei on D, getting rid of Kotkaniemi's cap hit in the process would be a coup.

Canes don’t even consider that. Canes can just go after another 2C and run KK at 3C, where he would truly excel. Nothing of any true value to even consider moving Pesce or KK anyway.

Leafs cant afford to take on a bad contract like KK's for that long. And could just go after Pesci in FA at the end of the year for free. KK adds nothing to the team. Similarly. Canes really get nothing out of this other than a cap dump. Which is useful to them. But no reason for TO to do them that favour AND give up Liljegren. Who is the only really valuable piece there. Take him out, and maybe . But I doubt it. KKs contract is just too bad.
