It’s pretty simple to me. The main issue with Rempe, again, is he’s so big and fast that he needs to pull up and brake as he hits vulnerable players. CK gets flak for not crushing guys in vulnerable spots, but he used to get the same treatment from refs like Rempe is. He’s learned when he can level guys- specifically when they’re mostly facing you, upright, and not going to end up flying headfirst into the boards. Otherwise finish your hit while braking so the refs recognize your intent not to injure. Rempe is so strong that he can still impact the play without leveling a vulnerable player.
