Blocking with Loskova

Hi there. I haven't attempted this one, but in the past when I've played similar objectives, I've taken a penalty so maximize those shot blocking opportunities. It sounds like you're trying that. Also, blocks would count just by using your body. Diving and dropping to a knee should also work. 

Are blocks not counting or are you just having a hard time actually getting in front of the puck?

I position locked, let my team break the puck out while I stayed deep in our zone, I'd call for passes when defenders were between us, resulting in bad turnovers, then I just got to the net and tried to block. Took me 4-5 attempts but eventually got the 4 blocks.
