I find it interesting that you call the BIG defensive player of the year, and a center who will break several school career records this coming year "Above average". I find it interesting that you think Vince Edwards "Above average". Have you really looked at his stats compared to all other freshmen in the country? I just can't agree with your assessment of "above average" when you talk about these kids.
Remember, when you talk about kids that fall by the wayside, or come off the bench, you have 13 scholarships, but start only 5 and have maybe 4 the are regulars off the bench. That means every class will have some fall out. You seem to think that is a bad thing in your analysis. I think you are blinded by too narrow a focus on Purdue and too little of a broader perspective across other teams. They have the same dynamics as Purdue, with regard to these happenings. They just don't finish tied with a FF team for 3rd in the BIG.
I'd say "production " has exceeded the expectations of each class in the 2012-2014 period. Classes from 2008-2011 were poor. Funny how you can see the same dip in recruting in Football and WBB also. Wonder what those dates correspond with in our school administration?
