If Fil is out I'd love to see Edstrom in his spot, just do it, don't be all NHL coachy about it and say he hasn't played center in the nhl yet, who cares, he's 100 % better than Brodzinski in that spot, let Brodz play 4th line where he'll be effective as well. Edstrom is the internal answer to the Chytil problem, it's early in the season, get him used to it. Cuylle and Kakko can help by committee to make the transition easier with their defensive play
