You can't be this biased? You are having two different conversations with yourself pal.
1) Historically, where does Illinois rank in college basketball?
2) In terms of current status of the program, where does Illinois rank in college basketball?
ANY NON PARTISAN analyst of college basketball would answer those questions very differently.
Historically speaking, sure, Illinois has had some great moments in their history...but what does a "big name" coach coming into the program give two-shits about that?? You need to recruit the current crop of high school talent to be successful, and that's universal language at ALL programs. Do you think some 6'8" shooting guard from inner city Chicago who scores 50 points a game in AAU ball has either 1 ounce of care or worry about how good Illinois was 20 years ago? Or would you suppose they'd be more keen on who they were watching with their friends last year play in the tournament??
You're very out of touch with reality my friend, and even if you're going to care about all-time, that's obviously very subjective. This list has them ranked like 24th all time. The bottom line is that coaches are leave programs to new ones because they feel they will be able to have success there. I think a coach would be lucky to get the Illinois job, it just has to be the right guy. Like Bo Ryan at Wisconsin...a guy who will get in there, get his hands dirty and win games. Although, Illinois will have to recruit much better, etc. You are wrong in that you're trying to have 2 conversations with yourself while everyone else is trying to present only 1 of the two. In that, they are right....today, as you read this sentence, Illinois isn't close to a top-20 program in the country in terms of where they sit today w/ talent, location, expectations, etc. They just aren't.
