Cat/Strome/Kane doesn't work. There is no real defensive capability on that line and with how the 'hawks are right now, they will be chasing, as opposed to possessing, the puck. We saw a ton of that last night and against Vegas. As
@HSBOB mentioned as well--throw Shaw out there with Strome and Debrincat--he'll keep pucks alive and do the dirty work. Maybe even a header goal if we're nice to him
. Still, that can allow Strome and Debrincat to maybe focus more on the offensive part of their games.
Koob, Being more Mini-Hossa than Saad was in his latest go-around, should compliment Kane's game nicely and finish what Kane sets up.
Right now though that Highmore/Kampf/Carpenter line works. It has chemistry. It may be nothing more than a 4th line but it's the most we got anywhere on the ice right now. Don't break it up--give them more time if they play well but sometimes chemistry counts for a lot. I'm not sure if you followed the 'hawks back when, but we had a 3rd line to envy: Ladd/Bolland/Havlat. They were a 3rd line that performed like a 1C. Sure, we could have split that line apart but Q, being the savvy coach that he was, kept them together and gave them more icetime. no reason we can't do the same for our currewnt 4th line.
