I think Kadri would look good setting up Grabo and Kulemin on the second line. Macarthur did a good job a couple seasons ago setting them up but last season his assists numbers went from like 40 to 20. Not putting that lines struggles on Mac but I would give Kadri a chance, and Mac will be effective on the 3rd line. Just run the hell out of those top 3 lines.
Lupul - Bozak (uhhhg) Kessel
Kulemin - Grabovski - Kadri
JVR - Connolly - Macarthur
Brown - Mclement - Komorov
