What a stupid thing to dedicate thought to. Just get rid of the shootout if they're going to take moves away. I mean what is the point of the shootout anyways, besides entertainment for the fans. The only thing I can understand is contact with the goalie, in which case they could implement a strict "no contact" rule - not ban a specific move.
Get rid of the shootout and bring in the 5min 3 on 3 OT, or whatever was being proposed a couple of years (?) ago.
