You can call us delusional, but that's simply not true. Before Bruce Weber took us down the shltter, we were playing for a National Championship after winning 4 out of the last 5 Big Ten championships, 2 of the last 3 NCAA Tournaments and making 19 out of the last 23 NCAA Tournaments and finishing ranked in the top 15 nationally for seven straight season (two of those in the top 5). There is no feasible reason, with our tradition, fan base size and resources, that we shouldn't be alarmingly better than Weber and Groce (our last four coaches before Groce won at least one Big Ten title ... I think it's a short list of schools who have been that self-sustaining), and expectations are higher at Illinois than at Purdue or Iowa. They are AT LEAST equal to the ones at Ohio State.
Again, call us delusional all you want, but our expectations are pretty damn high. We've been really good on multiple occasions over multiple decades, so we know it's possible; we expect a coach to return us to that level, and we can pay the big bucks for it.
RE: This hire, we'll see if it works out. I think he's a good coach, but I'm sure OSU wanted someone a bit more established. If I were an OSU fan, I guess I would be cautiously optimistic.
