Pitt is a semi private/public school, Pennsylvania has unique methods of funding, Pitt gets some State money but is not administered, runned or included in the State Education system
And I have addressed USC, repeatingly, and the other schools were employed hopefully as examples how private schools and even many public schools have selected not to compete at the playoff level due to the cost, the schools, especially those private schools without access to State money to fall back upon, have prioritized their funding, as USC apparently has and I'm predicting will continue to do, what do they have to lose
Your just seeing everything thru nostalgia, again, there are only seven or eight, ten tops, schools that have decided that they will fork over the millions necessary to secure their alumni a playoff caliber football team, and in addition, the vast majority of those schools are in geographic regions that really don't offer a whole lot of anything else in terms of athletic competition
