I think it's possible that our defensive numbers could be in line with this years, just because it may take a year for him to adjust to the Big XII's style of play. With our departures though, I can't see them being any better than this year.
Yes, this is part of it. Granted, it will take significant individual improvement and understanding of the Lowery/oscar system by the returners. And at least 1 (probably 2) of the freshman will need to be 50% minute contributors. Again, I'm going off of the fact that oscar's most consistent strength at Illinois was defensive efficiency, and especially eFG% defensive.
If he continues to play small, the numbers could be more like this year's for K-State though.
