Not sure that JKO parallels are sound... The approach appears quite different in important ways.
He played more than Cooley last night, including on the PP. So as far as "usage", it's perhaps more about linemates & chemistry than ice time and situational deployment.
I fully agree that the Anderson/Newhook/Slaf combination appears unproductive (for all 3), but it's not like Slaf is getting the 4th line treatment or yoyo treatment (like Ylonen, or JKO did).
Interestingly, JKO who is thriving this year, is still under 16min/night and on the Canes 2nd wave PP...
Habs PP sucks, and our offense remains challenged in lacking any quality playmakers after Suzuki (Monny & CC & Newhook are more finishers than play drivers). Dach going down really hurt us in that respect... And because of where we are at in the process, they seem ok with taking our lumps rather than aggressively trying to plug that hole.
Dvo, while no saviour, should help things if he can get in rythymn quickly and stay healthy.
