You deny being delusional, then spend four sentences proving it. Nebraska has had FIVE opportunities to hire an elite coach since 1997, and hasn't even come remotely close to anything that could be categorized as such.
"Nebraska gives a coach every advantage imaginable..." Massively delusional. What advantage does Nebraska have? It's middle-of-the-road facilities that look exactly like every other school? It's old stadium that takes 45 minutes to enter, an entire quarter to pee, and has more seats in the end zones than the sidelines? The winning tradition that disappeared four years before recruits were born? Loyal fans, who have as late been booing and leaving early? Media rights that everybody else has? Dull uniforms? Tired tunnel walk? World-class pheasant hunting???
The only two things that matter are money and a fertile recruiting base. Nebraska has the money, it definitely doesn't have the recruiting base. The state produces eight recruits a year, at best. There are single high schools in Texas that produce nearly that many in a given year. The surrounding states are devoid of talent as well. That means selling the snowy cornfields and riveting Lincoln nightlife to guys in California, Texas, and Florida.
Get ready to be really, really disappointed.
