I'm glad actually the Oilers didn't have the "perfect roster on paper" last year because it breeds mental toughness if you continue to fight through it.
You either cry about bad goaltending ... or you suck it up and play through it. You either cry when your no.1 D is injured ... or you suck it up and play through it. 2nd best player in the world badly injured ... well cry about it ... or play through it.
Calgary was not as mentally tough as the Oilers in the playoffs, and it showed big time, they were not used to dealing with adversity or playing against a team that wouldn't back down from their huffing and puffing.
Toronto IMO needs to learn this, they still crater and go sulk rather than get pissed off and fight back in the playoffs. It's not all about skill, there has to be a will behind it.
Even in the Colorado series I felt they fought hard and battled, but the hole that Nurse's injury left on the back end was too much to overcome against a team like that and Draisaitl playing on one leg was always going to eventually take its toll too. Oilers could've rolled over and died multiple times in the post-season, it takes mental toughness to play through having a lot of crap thrown your way, but that's a good thing for a team to go through if it doesn't break you.
Maybe that's an influence Ben had on the locker room (how big are "hockey problems" when you see a 5 year old kid battling cancer, who cares if you're down 0-2 in a hockey game compared to that, who cares if you're even down 1-4), maybe it's the wild up and down drama of the regular season, maybe it's the voice of a new coach, maybe it's just a superstar who says "f*** this, I'm tired of losing" but in the end IMO the Oilers grew from that and they will be a tougher squad as a result.
