Ok, how about we drop out foreigners and just go with American-born best all-time squads? That would eliminate Arkansas, Washington State, Iowa State, Providence, Alabama, and the fabled UTEP.
So, it's between Colorado, Oregon, Stanford, Wisconsin, and maybe an Arizona or BYU (though the higher age factor kind of eliminates them in my book). Adams St. from NAIA-Div II for the win in their category.
