I think Engvall will be key in his development into a 3C.
Also, I don't understand why AM, Willie, JT and Marner got to be in the top two lines.
Willie can play C, while Marner can be the line driver on his own line.
Hyman-AM-Willie
Soup-JT-Marner
Robertson-Engvall-Kap
or
Hyman-AM-Willie
Soup-JT-Kap
Robertson-Engvall-Marner
or
Hyman-AM-Marner
Soup-JT-Robertson
Engvall-Willie-Kap
In the lineup where Marner is on a line with Engvall and Robertson, Engvall just needs to win draws and be solid defensively and let Marner do all the offence thing while Robertson just needs to get open. The JT line is pretty much the shutdown line.
The lineup with Willie at 3c, all three lines are solid and can score and skate. Assuming Willie can be a solid C.
