Player glitching when trying to one time in front of the net

Hi there. Are you talking about Benn? Most likely, that's due to the contact they're making with the goalie.

look closer, he’s twitching until finally shoots the puck. 

That is the main reason I don’t play online anymore because of as I call them Cheaters exploiting using glitching moves that can’t be defended at all if you poke check your in the box they protect the puck up and down the ice if you poke in the box you go. If you hit you bounce off them. To me that called bad sportsmanship. EA allows it. EA has not anti cheat or a in game reporting system at all in game to report the cheaters. Cheating should be banned from gaming. If you use cheats or anything like Zen EA should be banning them from the game. 

Yes. Twitching from the contact they're making with the goalie. I'll pass on the video for you. Thanks.
