is a funny argument. Who doesn't struggle against good teams? Duke "struggles" against good teams. For all our "struggles" we are a total of 6 points from being undefeated this season. I will take that kind of struggling because it means we have a good team.
The other funny argument is - "yah... But how good have we been since losing one of our best players ever". Ummmmm Pretty good actually. How good has UCLA after Wooden retired? When you lose the best player you have had in years you generally are not as good the next season.
