If you forget where he's drafted, Kakko is an incredibly valuable middle six forward when healthy.
Key being, when healthy.
He seems to be out of the lineup a lot, but when he plays consistently he's a possession driving forward at 5v5 with elite defense, who can very reasonably hit 20 goals and the 40-50 pt mark, as he was trending towards that heading into last season. At 23 years old, it's very easy to see that if he stays healthy, he has a lot of room to grow into a much more offensively gifted version of Jesper Fast. I know that isn't what we thought we were drafting, but that's still an incredibly valuable player to have on the roster.
If we can sign him at under 2.5m, and the team thinks he can stay healthy, I think keeping him is a no brainer.
