This is pretty much my feelings on it all. I am not in the least sad to see him go. Heck back when they solved the last lockout I had hoped the team would use a compliance buyout on him. And then in 2017 I wrote this for Gone Puck Wild. If anything, hearing it was finally over brought a smile to my face, the way it might be when you finally pay off a car or something like that. Not a big smile, but one that was a sign of glad that is now behind us.
Like Hockey_78 said, Mikko was very well paid in his time with the Wild and more or less given 100% autonomy and top ice time for the majority of his career.
I don't think we ever saw Mikko really stand up for his teammates despite being team captain. We saw him yap at guys from time to time, but we didn't see him do anything really selfless for the team.
But hey, because this organization hasn't accomplished much in 20 seasons, lets retire his jersey!?!? I think there is a fair chance I might just miss paying attention to that cheesy and predictable Wild moment.
