There's always conversation around the ACC expanding with Big East teams and how much of a difference it makes, was it worth it, blah blah blah.

It's NCAA tournament time and I present you exhibit A:

Between 2006 and 2014 (9 NCAA Tournaments), the ACC had 7 teams reach the Elite Eight (UNC x5, Duke x2)

Just the last two years, 2015 and 2016, the ACC had 7 teams reach the Elite Eight (UNC, Duke, Louisville, Syracuse, Virginia, Notre Dame x2). So 4 of the 7 can be attributed to the newbies. Syracuse became the first non UNC/Duke team to make the Final Four from the ACC since Georgia Tech in 2004. I'd say the difference of the additions is significant.
