I have no interest in penalties, or the skills/nerve required. They almost always follow a tedious 2hours of overcautious play. I fell asleep twice during that game, and I regard that as useful zzzzzz gained.
I don't know the answer, but knockout football seems doomed. I'm so disappointed after so many great group games. Only the Germany semi was at all interesting, and that ceased to be a contest quite early on.
