That hard shot is only thing Seider is missing. But in nowadays hockey, defenceman point-shots have lowest percentage to go in. Smart defencemen doesn't have to use them, you can be a threat in many other ways. Skate for a better spot, on the medium-sector, "buy" the better percentages and shoot with a wrister. Smarter hockey. Seider-hockey.
Defencemen point-shots will always need a good screener be to be synchronized with those shots, like Holmström was. Otherways those are useless. It's complicated to understand, but the shooting ability or power is not really a thing, imo, more of shot timing is the real skill. And that will need hockey IQ Seider's brains are full of.
And if you go to ask from a goalie, they all say weak shots are the worst for a goalie. They hate them, because they make them uncomfortable. They hate the "falling leafs" coming slow. Goalies prefer hard and linear shots, which are easier to see (if not screened) and against whom they have the endless routines.
As a smart guy, Seider can develop a "slow shot", always just thrown weak behind a screen (John Klingberg does these a lot) or offered for tip-ins. That's exactly how he scored his lonely goal in SHL last week.
Hard blasts pretty much belong in old NHL. They are just "ooh" -factor, for entertainment. And it's fun, and give some extra feeling, when a big bang goes in. People believe those are the tough shots to be catched, but they aren't any more effective than weak non-linear shots. Both have to be completed behind a screen, and that screen and screen/shot timing is the thing, not the shot. Defenceman has to have the eye for the shot timing.
