The Mighty Duck Man
R-E-L-A-X
Trying to look at this with a glass half full. Our current forwards are actually right up Carlyle's wheelhouse.
Dominant First Line: (Perron) - Getzlaf - Perry
Offensive Second Line: X - Rakell - X
Defensive Third Line: Cogliano - Kesler - Silfverberg
Grinder Fourth Line: Garbutt - Thompson - Wagner
This was my first thought too.
Having a fourth line that good is probably pointless under Carlyle, he leans on his upper lines quite a bit. He'd likely lean on Kesler defensively too much, which isn't to say Kesler can't handle it, but it's not using that line right.
