I don't think he made the right decision but I'd be curious to hear how others see it, especially those who are optimistic about Mateychuk's chances of making the team out of camp next year.
It looks like they are either running a diamond or collapsed box. Assuming it is a diamond, I don’t see anything wrong with it (the stick positioning). He’s trying to cover two passing lanes, with an active stick. Takes away the crease, reads the forwards eyes, then takes away goal line extended. Then tries to close the space down. However, if it’s a diamond, the pass to the low F at the 18/19 second mark cannot happen. He needs to be wider to take away that pass - as it directly breaks down the PK, giving space to the F at the dot. In that case, it’s on him.
On the flip side, if this is a box PK, I think the high forward dropped the ball on this. He overcommitted to the D at the blue line and got too high in the zone, allowing for the pass to goal line extended. Obviously in a box scenario you don’t want your D going out to defend the faceoff dot. So I guess it depends.
Since his draft year, I've rarely seen him go down on his knee and land his stick sideways in attempt to take passing and shooting lanes away. I think he could've done that and got a little closer to Marques to prevent the goal.
Depending on the coach, this sort of style is being phased out. In general I think it takes guys out of the play more often than it works.
I know it’s not the same, but this is a good example of what I mean (in this case a player slides to take away a lane)
