There is actually a very good reason why Hietanen and Lindell's quality of shots has been so abysmal on PP. It's all about the positioning of other players.
Our PP formation is not ideal for trying shots in the blueline - there is no player to draw the defensive diamond's point man away from the blueliner, the player in the middle is not ready to look for deflections, etc. That's because the formation has been modified to be optimal for the shots taken by the point shooter on the left.
If the Laine/Pulkkinen are meant to take the shots instead of the blueliner, why do Hietanen/Lindell so often take that shot anyway? They must have talked about it and rehearsed it, right? Well, let's keep in mind that hockey is an extremely fast game where players often have to make split-second decisions. More often than not, the game is played on pure insticts.
And if the blueliner's insticts tell him to take the shot, he often ends up taking the shot, no matter what the plan is - simply because they've done it so many times before in a similar situation. It's human behavior.
And what comes to Pulkkinen missing shooting opportunities yesterday, I did not see any either. For what it's worth, "Pulkkinen has the puck on the left side" is NOT a "shooting opportunity" in and of itself. In most cases, he was either at a bad angle or the defensive player was too close. Not to mention the "shooting opportunities" are often built as one-timers, and if Pulkkinen for some reason or another just had to take possession instead of unleashing a shot, that's more the passer's than shooter's fault.
