That's a pretty bold move, if Big East commissioner John Marinotto complies with the wishes of the football coaches. On one hand, gaining the Irish would give them a boost in television exposure and revenue. It would also give the Big East nine football-playing members, which means a balanced conference schedule like the Mountain West has.
On the other hand, this may be an attempt to indirectly save the league from completely imploding. If Notre Dame's other sports programs are cast off from the Big East, they would not be able to survive as independents as their football program has been able to. That might be the impetus for the Irish to finally join the Big Ten as that conference's twelfth member.
The thinking there being that, if the Big Ten gets to 12 with Notre Dame, that they cease looking for other new schools. Many of their potential targets right now are Big East schools- Pitt, Rutgers, Syracuse, etc. Getting back to Bennett's blog, Edsall also said that if the Big Ten were to take two of those teams, that "the Big East is all done".
