I disagree with this. The medium sized schools are the ones pushing for rules changes, transfer portals, etc ... to get an advantage. The problem is, the advantages soon skew to the larger schools with deeper pockets and resources. Quoting Nick Saban re the transfer portal (being against it) ... "Are you SURE you want to do this?" He knew that ultimately, it would tilt the game even further towards a few schools. But, he was outvoted.
Greg Sankey, commissioner of the SEC, spoke to this a few days ago. The NFL is successful because they have four networks supplying a product to the entire country and a very organized approach to scheduling games and post-season play.
The college game does not. Conferences pursue the game from their own self-interest with the NCAA larger a bystander. So what has happened is that unlike the NFL, the college game has REGIONALIZED with high viewership and fan interest in the South, some interest in the midwest and virtually none (by comparison) on the West Coast. Sankey's frustration is that the NCAA takes years to address issues that a conference can address in days.
I think what you are witnessing now is that the SEC will ultimately expand again and admit Michigan, OSU, probably Notre Dame, USC and Washington with a goal to create the college game in the image of the NFL ... with TV packages and playoffs to boot. So yes ... the best teams will create the best college football experience and probably a better product for everyone. The smaller programs will end up being more local and more regionally driven.
