Probably the goalie and extremely defensively-focused coach in me, but Mikko's lack of engagement and pedestrian shifts would be a killer at 2C on a consistent basis.
More than anything, a good center has to be engaged and active. Whether it's the wheels always moving like a Horvat or Larkin... active sticks like ROR or Bergeron… your center needs to be involved.
Mikko, in my honest opinion, legitimately takes off about a quarter of his shifts where he glides around and takes two or three strides in 30 seconds.
You’re either cramming a square peg into a round hole and forcing it to work, or you’re going to be awfully frustrated with our top two centres being completely disengaged on the defensive side of the game.
Just my $0.02 CAD.
