While there have been a lot of changes in college football since Dodd's days... by and large they have favored the 'little guy.' If you don't think that's true, then you aren't paying attention to the FCS teams beating FBS teams, or the surge in long-irrelevant programs (like Oregon and TCU and Baylor... Baylor!!). The limits on scholarships, the limits on practice times, the increased likelihood of stars leaving for the NFL, the equal media rights payments, etc., have all made it easier for teams to compete with the Notre Dames and Nebraskas of the world. I think you can make the argument that both integration and the influx of Northerners just as professionalized sports came to Atlanta both had a huge negative impact on GT football disproportionate to the impact similar changes had on other programs. But by and large the structural changes in the sport have contributed mightily to a more even playing field than existed in 1955.
