If the basis of your value on Danault is his offensive production then it is best you don't ask or comment about his value any more
Danault is one of the best shutdown two-way centers in the NHL, his offensive production is not why you want him; and he is significantly more valuable than even Domi (assuming contracts were even).
You could put a player like Kakko on his wing, and Danault will soak up all the defensive responsibilities and make Kakko just better inherently by not having to worry about backchecking as much.
