The only one of these proposals I like is getting rid of the attainable pass rule. I think that rule's stupid. I also think the rest of these proposals are stupid. In order of stupidity:
1) Icing calls while shorthanded -- I can't even put into words how dumb this is.
Agree - Completely ****ED.

(out of 5)
2) Getting a power play even if you score on the delay -- This essentially makes the penalty a double minor if the team scores on the delay. Why?
3) Stricter contact to the head rules -- I understand protecting players, but making contact to the head an automatic ejection is going too far.
Overzealous and kneejerk proposal.
4) Hybrid icing -- If this would be consistently called correctly, I wouldn't mind it, but college hockey refs are far too incompetent to make this rule work.
OK
5) Changing ends before OT -- The NHL does this, so it's not unheard of. I just don't like it.
OK
