But I think that IS putting himself in the best position to facilitate.
Kakko's strengths are along the wall and what made him such a menace as a prospect was his ability to win a battle and go to the net and make things happen. That part of his game has completely evaporated as a NHL player and I refuse to believe that he isn't capable of it. If he's winning battles in tighter spaces, he can force his way to the front of the net. Putting him on a line that can support that will hopefully rekindle some of that in him (see: engaging Kakko, as you want.)
Plus this has been the most tried and true way to create offense forever. People become enamored with the high flying shit but good structure snuffs that stuff out right away. This style of play is way tougher to defend since it entirely depends on your ability to win these battles.
It may not work and there are other combos I wouldn't mind seeing (Kreider-Zib-Kakko worked too) but if you're hell bent on spreading things out and separating Kreider and Zibanejad, I'm not really seeing many better alternatives.
