ACC wants Notre Dame to commit to playing 6 ACC teams per year. They already routinely play Pitt and BC and has played Georgia Tech and Miami frequently in the past, so they wouldn't have to concede a ton (and they'd get to play in areas where there are a lot of Catholics vs Northeastern teams and areas that are great for recruiting vs Southeastern teams). I'm sure that Notre Dame games would be considered marquee match ups and would move the needle a little, but I'm not sure how it could be enough to augment 14 other teams in a significant way. I guess that is the ACC's job to sell.
Am seeing that the Big 12 would also like to play 6 games vs Notre Dame, but Notre Dame is requesting that they play 3, with a yearly game against Texas (to be played on Thanksgiving weekend) and a strong preference to play Oklahoma each year. Big 12 officials feel like adding Notre Dame (w/ 3 Big 12 home games) would be enough to get FSU off the fence, which together would boost the Big 12's TV revenue.
Who knows how reliable and whether, if it is true, it will be true tomorrow, but it is coming from a guy that has been reliable in the past and threw out the possibility of Dana Holgorsen becoming coach in waiting a few weeks before new broke (when it seemed like an absurd notion).
