Why Scott?
You prefer it end in a tie, or they keep playing?
i like the NHL way. Regular season games they play a short 5 minute sudden-death OT and if there are no goals, then they do a shootout. I get it. Time. TV time and all that. So in soccer, they do the shootout already. No need to change to a 5 minute sudden death but for goodness sake, why settle a World Cup on penalties? I fucking hate that. Don't you?
I say play 10 a side in OT and play until someone scores a real goal. They know its going to go to a shootout so they just waste time and take their chances in the shootout.
