Swearing, anger, tears, and other outburst of emotions are indicators that someone may be concussed. Basically, it's unusual behavior that is the indicator. McDavid is WAY too valuable to sweat him missing a few minutes of a game in December. EDM fans should be happy that he was taken off and checked out. Saying that he should " tough it out" is the sort of thinking that destroys careers. We're talking about a possible brain injury, FFS.
I saw a guy who landed awkwardly on his chin? And appeared shaken up and dazed afterwards. Good on the NHL, and boo on the Oilers, for not taking care of the most precious resource they've had on the team since Gretzky. What did he miss, two minutes of actual ice time?
Good point on the fighting. Unfortunately, guys like Kassian and Gabriel aren't being protected by the league.
FWIW, I thought EDM played very tough front of net D, which is something they haven't done for years. Wild were trying to get pucks in to the goalie, who was giving up rebounds, but big guys like Nino, Staal, and Coyle couldn't get loose to get them or deflect pucks. Not glamorous, but it's going to keep you close in games that in the past would be out of your reach.
