All of the ND hate on here is a bit ridiculous...why did everybody think that ND would eventually cave and join the Big Ten? Sure it is still a possibility (I am a ND fan and I actually want them to join) but there are many LOGICAL reasons for the Irish to join the ACC.
ND has always been able to recruit nationally, do to their national schedule, but if they join a conference that will no longer be the case.
The South East and Mid Atlantic regions populations are growing much faster than the Midwest. If you are going to be tied to a conference for the next several decades you want to make sure there is a steady stream of talented players for you to be able to recruit..and nowhere is that more prevalent than the south. They would still be able to recruit in Illinois, MI, IND, and OH, but would now also have access to FL, GA, SC, NC, and VA talent pools.
Sure the Big ten would make ND more money but ND does not need money. They have $6.1 BILLION endowment and tons of alums..the ACC would provide more than enough.
