I know there's not a ton of fan support, but Illinois is one program that is a potential sleeping giant. Huge population in-state. No other in-state schools to compete with. Good football talent to recruit. The right coach could turn them into a power..
The sad thing is, the support is there ... when they're winning. In the early 2000s during the Sugar Bowl year and the year after, 76,000 were showing up for big games, and we had a great showing at the Rose Bowl in '07-'08. TV ratings those two years were through the roof in the Chicago market. Unfortunately, our program has been downright painful to follow, and until/unless we put a product on the field that isn't an embarrassment, only the diehards and locals will show up.
Illinois wouldn't be a "power" with the right guy (like we were/would be again in basketball), but we would be consistently competitive, which is all we ask. We haven't been consistently competitive for over 30 years.
SirIllini is the king of hyperbole, and I hate reading his posts where he constantly rags on U of I, but he's right: Illini fans and Illinoisans are p*ssed off, and they should be. We're one of the best public schools in the nation, we have a massive alumni base and we're the flagship school for a big state (I don't care what some jokers say, I've lived here my whole life, and there are only a few counties in this state where UI isn't the most popular team, and that includes Cook), and what do we have to show for it? Crap.
