Giving players suspensions for attempting clean hits but slightly missing discourages the throwing of clean hits in the future. It sucks.
Honestly - and I'm sure I'll get called soft or whatever - this hit isn't one that should be attempted. These plays where you're coming from the numbers side of a player to make an open-ice hit are generally just poor decision making. You're absolutely asking for trouble, excessively endangering the target, and it's a reasonable likelihood that you miss and put yourself out the play; players should really know better by now.
The player has to try to kind of loop around and change the angle of attack so that they're hitting the guy from the front, and the target becomes such an impossibly tiny sliver of body, especially since angle of approach means that the player's head is going to be prominently hanging out there and almost impossible to avoid contacting first.
The specific angles and level of sheer violence on impact are obviously different but this general angle of approach is what gets you the Cooke on Savard hit, or your Colby Armstrong special, where the hitter is coming from the numbers side which makes the angle of attack such that the receiver's head is almost inevitably going to take the brunt of it. It's just so hard to catch a guy properly coming from that angle across the body because there's just so little target available to you, and you're trying to make so many adjustments all at the same time that you tend to end up kind of reaching and lunging back to make contact rather than moving straight through their body, and that's where you end up getting into trouble.
DOPS being an inconsistent shitshow is a separate discussion, but I have no problem with this in isolation.
