When I was being taught math, they told us often that "You can compare apples and apples. You can compare oranges and oranges. But you cannot compare apples and oranges."
This is another case of your spouting off without reflection. While the statistics have changed year to year for Purdue's team, so has the team. Last time I looked, there are 5 players on the floor during a game for each team. This year's five is different than last year's five, though there is a carryover in Edey. But to attribute all of the change in any team variable to one of the five is not valid logically. The acts of the other four affect the result, which your post ignores.
There is nothing to defend because your premise is laughable. That is because the premise of your claim has no logical validity. Of course, as has been demonstrated mathematically in another thread, your posts and opinions are wildly divergent from reality. But what else is new?
