What I think the NHL needs is more collaboration between officials, so when we have the common situation of the back ref making a sh!tty call, the refs and linesman can get together and decide to pick up the flag. Or if one ref sees a penalty and raises the arm, but another sees that it was a blatant dive, they can conference and call only the dive instead of the non-penalty. (For example, stick missing the face but the player throws his head back.) Embellishment in the case of an actual penalty should be called as-is, offsetting penalties. I agree there should be fines, but only for blatant, no-question dives.
