I had not really thought about this but the evidence you present is irrefutable. The rest of us literally have no chance of competing for titles which really begs the question for most programs, what then, is the point? To the names you have listed there are a few elite factory type schools that have not tasted glory with a national championship but certainly have the resources and the recruiting bases to do so. LSU, Nebraska, Texas A&M, Notre Dame, UGA, Michigan, and Penn State to name a few. So realistically you have about 17 to 21 teams that are in the universe of national title contenders.
I am beginning to think with the rampant cheating, paying players, academic shenanigans, bagmen, and the like associated with these "institutions of higher learning", perhaps it would be better for certain teams to cut ties with the NCAA which has become a laughingstock and form their own league.
I am thinking primarily of colleges that are willing to maintain a semblance of academic integrity, adhere to an agreed SAT and high school scholastic record standard and simply withdraw from the rat race of football factories that are no better than pro football minor leagues. To be sure, this is admittedly nothing more than wistful thinking on my part but I am thinking about primarily the private universities like Duke, Wake Forest, SMU, Northwestern, the military academies, Tech, Vanderbilt, Syracuse, Boston College, Pittsburgh, perhaps some others like Virginia, Tulane, Temple, and others that see through the hypocrisy that is currently going on. On the other hand, it is likely that the lure of easy money would be too hard to resist and therefore the aforementioned would continue to be punching bags for the factories to varying degrees.
