that makes too much sense to actually happen.
but in reality, the tv revenue wouldnt be enough to warrant it. that's too many mouths to feed. that's the reason they arent adding wash and oregon now, they dont change the revenue equation and would just lower everyone else's take.
the only way to get notre dame would be to lock them out of scheduling other big ten teams, other than that they'll just live off their games with michigan, usc, stanford, etc and take all the money for themselves.
btw, how lucky are northweterrn, purdue, indiana, RUTGERS, for being in the big ten? they'd be nothing if they werent in the conference. they'd be kansas, an afterthought.
