I think there is a difference between running up the score and what happens in these situations. If teams continue to push hard all the way to the end of the game, play their starters, run fancy plays and beat a team 16-0...thats running up the score and I frown on that.
If the team benches its top players, or limits their ice time considerably after they get up, implements a five pass rule before your allowed to shoot, changes game strategy, tries new lines...etc and they still manage to score 16-0...they aren't scoring to be ****** bags, and have let up on the team. I don't see as much wrong with that.
I know you don't want the comparison...but I could barely stand to watch the US game yesterday...it was so boring, it was hard to watch a team be so outmatched..and at the same time watch the other team try to play at a lower level.
Another comparison you don't want...When my basketball team got beat 75-8 last year...the coach kept his starting 5 in the whole game, pressed us the whole game, ran designed 3 point shot plays at the final buzzer...he was a ****** bag. When my team was up on another team 20-2 after the 1st quarter..i sat my starting 5 the rest of the game, ran a base zone defense...eventhough we still won 60-12...I don't feel like a ****** bag.
Superior will very likely lose a tie break due to goal differential...so there is something to be said for scoring as much as you can.
