I can see that. I can envision a world where the Alabama's of the world are using schools like Utah State as minor leagues. Send us your late bloomers! Bama gets them to run same O and D and shares tips on strength and conditioning. Then some kid who didn't develop fast enough for the SEC in high school but catch on later can transfer in.
I think if the super leagues of the future go forward there will be fewer blowouts and therefore less garbage time to get the younger kids real game experience, so the elites will depend more than ever on transfers.
