The plan outlined above is actually the only one I've ever seen which ND would have several incentives to accept. ND isn't just independent for the sake of it. The school remains an independent so as to secure the freedom to schedule whomever they want, keep all the proceeds without sharing, and get a sweetheart access deal to postseason play.
The plan above gives ND a 6-6 split between conference and OOC games per year. It also involves at least 3, basically 4, of those 6 conference games being traditional rivalries ND would schedule anyway. The other 6 games are more than enough to play Michigan, USC, Sparty and rotate 3 other slots to play the likes of Miami, Texas, OU, etc. Furthermore, the plan would allow ND to bank both its complete NBC contract and [presumably] a limited slice of the BE's football contract -- say, the value of any ND games not part of their existing structure and obviously a share of the championship game revenue. It also offers the chance for an additional home game if making the championship game as the top seed. As for the post-season, not only would ND remain an attractive option for an at-large bid anytime the Irish qualify but didn't win the BE, they could theoretically get into a BC$ game with an overall record of 7-6! How's that for sweetheart deal?! Furthermore, this plan would also stabilize the BE and guarantee the fat contract that would stave off the threat of ND needing a new home for its other sports.
In exchange for this generosity the BE could guarantee a big TV contract, keep the league together, and not have to invite some garbage like Houston. Those of us in the non-ND division have the possibility of hosting ND in our house for a blockbuster championship game.
Notre Dame in Fort Worth, first Saturday of December for the Big East championship. Tell me you don't love the sound of that, whatever concessions need to be made.
