I don't care about the cap space because it's coming off the books this summer anyway. It's so key to allow a space for Frattin and Kadri to play IMO. These kids need ice time. Ice time they won't get on the 4th line. These kids have way too much skill for that nonsense. I would try this.
Lupul - Bozak - Kessel
JVR - Grabovski - Frattin
MacArthur - Kadri - Kulemin
Komorav - Steckel - McClement/Brown
Still would be nice to trade MacA TBH. A third line of K's would be solid with Komarov - Kadri - Kulemin
They would draw so many penalties it would be ridiculous lol Teams would HATE playing against that 3rd line.
