He didn't put himself there. This isn't a sudden change of position like turning into the boards to avoid being hit. He's in the process of being hit by another player while controlling the puck. He already took all the precautions he can take, now he's half-trapped and still in possession. Zibanejad could easily seal him off or pick his pocket without putting his head into the wall, and at this point it doesn't matter if he made 100% shoulder contact, Faksa has no options available to him to protect himself.
There is zero, absolutely zero reason for Zibanejad to finish that hit like that. If you ever think "I'm going to hit this guy's shoulder with my hip" you're already in the wrong, I'm trying really hard to think of a justified scenario for that and I'm coming up blank. Seized a completely avoidable opportunity to violently put his opponent into the boards, Faksa has no way to distribute the force through the rest of his body or the wall because he'd only just done that. That's a vulnerable player, perhaps even by definition.
Or maybe this is fine, and I should call the coaching staff in D.C. up tomorrow and let them know that all the team's softbodies need to do is keep people on the tee for Tom Wilson to crank at will. It's a step away from tag team wrestling and totally avoidable
