The R Smith deal also provides some flexibility with Kakko if you want to move him in season or at the deadline. Similar to bringing in Wheeler last offseason - but I believe Smith will be more effective.
I think a lot hinges on health. If Smith, but more importantly Chytil is still there going into the playoffs it allows Drury to potentially move Kakko for a big top 6 upgrade. Although looking at the UFA list I'm not sure how many gamebreakers will be available.
However, if the result of Chytil staying healthy is providing Kakko with the skilled play driver he needs at center, then Kakko may blossom into a version of what we thought hed be and then there's no reason to move him.
