I was very disappointed in Muzzin and Rielly (especially Muzzin), when they didn't do anything about Matthews head-hit right in front of them. I love Muzzin, but you would think that a tough guy would defend Matthews. I think it might have something to do with Babcock telling them not to fight? That seems silly.
In terms of toughness and physicality, I do think it's time to add a Ritchie/Crouse type player. I have loved the rebuild and progress so far by Shanny, Dubas, Lou, etc. But now's the time to trade a skilled player for a slightly less skilled, but more physical player. Jujher Khaira or Alex Chiass0n are some good targets from Edmonton, and we could probably fleece them anyways.
Hyman - Tavares - Marner
Johnsson - Matthews - Nylander
Mikheyev - Kerfoot - Kapanen
Timashov - Khaira - Moore
Rielly - Ceci
Muzzin - Barrie
Dermott - Holl
Bolded: Need to play an aggressive, physical game while the non-bolded are fine the way they are.
