Because the way you talk, seems to imply you think they are equal playing fields
Equal playing fields? Yes. They’re both major universities that play high major basketball, both had been similarly mediocre when the current coaches were hired, etc. There’s nothing stopping ASU from hiring a good coach and getting good results, and as we’ve seen first hand there’s nothing stopping Illinois from hiring a mediocre coach and getting mediocre results
That notably isn’t at all what the poll says.
