A penalty on leaving your feet is the most horrible idea I have ever heard (other than making the nets bigger
) It's part of hockey and it's going to be a bitch of a judgement call. Can you go to one knee? Is it just to block a shot, or will you be called if you go down anywhere on the ice? I'm not a big fan of referee's being asked to judge intent - especially in a fast moving game like hockey. They blow enough of the ticky tack technical calls as it is.
At least the idea of not waiving icing on the penalty kill wasn't proposed... that would have completely changed the game in a bad way IMO.
I don't see why there HAS to be more scoring, but that's just me. The bad old days of the mid 90's trap are long gone and I am actually happy with the product for the first time in 10-15 years.
