The addition of UConn and Notre Dame is still the most logical move that The B1G could pull off IMO. It won't happen because of Domer Exceptionalism, but on paper it makes too much sense. The addition of ND would likely raise the overall share value for all members of the conference including The Irish upon their joining. UConn could be on a graduated revenue plan like RU and UMD initially were on and then ramp up as the conference has its next window of rights negotiations.
The addition of Husky M/W basketball, hockey, and yes even football would add value to the conference based on the quality of the programs and the increased exposure of the conference to the market. UConn and ND are currently the two most "available" programs from a contractual standpoint as well. Again, nothing happens because of ND, but damn it, it just works so well. Total domination of the Pacific Coast, Midwest, Northeast, and Mid-Atlantic Regions. In the early 2030's you work on peeling UNC and UVA or UNC and GT away from The ACC and close up shop.
