Watch the play again, obviously you missed something. I'll be a nice guy and lay it out for you. Watch the video and tell me where I'm wrong. The entire sequence started when McDavid had the puck.
- Garland knocks it away, McDavid then checks Garland. Its a totally legal check, both players were playing the puck. To the people calling this a "pick", it is not. It is actually a pretty smart move by McD because he realizes he is able to check him and take him out of the play
- Garlund is knocked to the ice. He realizes he can't lose his man so he essentially does an arm lock and drags McDavid down.
- At this point that it is technically a penalty. You can't hold the guys arm going down. I understand not calling it however it is hard to see.
- Garland continues to hold his arm for a couple seconds. McD is trying to get up. He gets frustrated once and gives him a glove to the back of the head. Ref continues to watch
- Finally Garland lets go McDavid then tries to get back in the play.
- Garland then GRABS HIM AGAIN and does a bear hug to keep him from getting back in the play.
- Then the crosscheck happens
It is a pretty plain and simple. Garland doubled down on essentially just holding McDavid for like 5 seconds in a pivotal moment of the game and McDavid snapped. I don't know why people are purposely obtuse about examining these things without understanding the context.
