The SEC made the first move toward building a super-conference when it accepted Oklahoma and Texas last summer. The Big Ten threw a counterpunch last week by adding Southern Cal and UCLA, a flex that shows that while the SEC had pulled further ahead, at least one conference doesn't plan to be left in the dust.
Both conferences will include 16 members once their new additions join.
USC and UCLA are set to begin Big Ten competition in 2024. That will stretch the conference's footprint from New Jersey to Los Angeles. OU and Texas remain on tap to begin SEC play in 2025.
