Whenever TV negotiations occur being additive can be manipulated if TV partner rights fees increase significantly.Also I really feel like the SEC and Big10 are happy with the current set up. The dust has barely settled on the previous realignment, I think it’s going to be much later then 2030 before see see other additions. Especially when outside of ND none are actually additive to the conferences
Plus ND is a different animal from a TV valuation perspective. So the Big 10 could add ND and lower TV valuation school and the package would be additive.
Finally, this battle for increasing CFP teams and Big 10/SEC dominating the number of CFP bids is the other aspect of being additive. Last year's 12 team playoff with ONLY 11 games generated TV rights fees that were in the ballpark of the Big10's annual TV deal.
