That will be the narrative for sure - 3 ACC, 2 B10, 2 SEC, and one Big east.
B12 shut out of the Elite 8 definitely wasn't expected by pundits. The other conferences will be claiming bragging rights over the B12, albeit the B12 has still been the best conference overall the last 8 years, as far as winning in March. But the ACC, who has been looked at as being knocked off the pedestal in recent years, will be puffing their chest out again with this year's results. But the B12 will be back with a vengeance next year!
