That is your opinion and nothing more. You have no basis whatsoever with that statement.
I think that's simply your opinion and nothing more. Purdue has more going for it historically than IU does and can get back to their winning ways with the right coach.
It is my opinion but it is also based in part on attending 2 games a year at PU for four straight years when my kid (2015 grad) was there. Those eight or nine games constitute a larger number than the vast majority of in-state PU grads that call themselves FB fans. Yes, I believe they will get better and yes, PU has enjoyed an advantage in FB over the years.
The funny thing in all of this is that over the last decade Fred Glass has beaten PU so very very badly at their own game and has a material advantage in every aspect of the sport that will only widen over the next two years.
After that...we shall see if PU can catch up.
