Kotkaniemi is a non starter for Dumba.
Right now, he struggles a bit, but Kotkaniemi is still only 19 years old, and showed a great deal of potential.
1c or 2c, something that we will need in the future, with Suzuki and Danault.
Domi is the odd piece. He's better than Kotkaniemi right now (by far), but ultimatly, I see Kotkaniemi as being better down the line.
We have to keep him.
I'd do either Domi for Brodin or for Dumba, tho. I'd prefer Dumba, as it would make Petry expendable, even tho I think he's much better than Dumba right now.
