I hate PKs when we win; I hate PKs even more when we lose. My preference would be to keep playing 45 minute "halves" until someone scores. FIFA substitution allows for only 3 per match. Someone would score sooner than later. But PKs is how The World does it, and they have done it that way for a long time. FIFA is not like the NFL where there are major rule changes every five years. Or, for that matter, the MLS where they evidently change administrative rules on a whim. FIFA is more like MLB, where change comes at a geologic pace. NCAA MSOC would gain relevance by adopting FIFA rules, falling in line.
