Deahler,
Sorry if I mixed you in with some of the "we won/loss but" crowd. You are a direct and to the point kind of poster and I'm actually enjoying debating the pk point with you!
Now to your post-I really don't see how the pk at the end of regulation is more "indicative" of teamwork vs. pk's to win. Does the team not share in some of the "blame" (I hate that word, but it's gotta do)of getting in the position to take it to pks. Also if one team makes their kicks (obvious advantage to the kicker) but the opponents miss theirs, that's a team loss. Both sides are equally matched at that point.
At any rate, it should always be a win for the "team" and a loss for the "team", whatever the situation.
