The AP's all-time rankings illustrate how much college football has changed during the past 80 years. While new-age powers like Oregon (No. 28, 293 poll appearances) and Boise State (No. 61, 127 appearances) are represented, so are bygones like Santa Clara (No. 77, 43 appearances), Holy Cross (No. 85, 39 appearances), Duquesne (No. 97, 20 appearances) and, everyone's favorite, Iowa Pre-Flight (No. 98, 18 appearances).
