Hockey happens so fast and it's hard to tell sometimes when players have intent or not.
With saying that, some plays can be super dangerous no matter who's on what end of it. During game three between the Edmonton Oilers and Colorado Avalanche, Nathan MacKinnon appears to catch Leon Draisaitl with a dangerous slew foot.
The NHL has given out sever punishment on similar incidents. Boston Bruins Brad Marchand was once suspended three games and Charlie McAvoy was fined earlier in these playoffs.
It's especially dangerous with the high ankle sprain that Draisaitl has been playing through, but it's hard to know if MacKinnon has intent behind it or not.
