Duals are duals...but they contain an inherent flaw that makes them very difficult to use as a barometer of a 'good' or 'great' team....many times the goal is to 'stay off your back' or to not get majored or TF'd.
The only place where someone must actually win to score points is in the current individual format. Even when the top teams meet, there are 3-4 matches where one wrestler is the clear favorite and the other is just trying to keep the point differential to a minimum. This means that you have 5-6 good matches(which have the possibility of turning into a bad, stalling, please don't beat me by too much proposal) and the others are clearly the latter.
Wrestling to win vs. wrestling to not get beat too badly...there is just no contest, IMHO.
