They did beat us that year, after all... To me, that's significant enough, given that we were at the lowest point in the Brian Kelly era, and enough was enough.
I don't foresee that ever happening again, unless Brian Kelly re-hires Brian Van Gorder and Paul Longo...
That being said, the 2016 Duke team was much better than their 4-8 record would indicate. They took out a pretty good UNC team (ranked top 20 at the time), and came close to knocking off ranked Va. Tech and ranked Louisville teams. Except for those two last games they lost against Pitt and Miami, they could have easily been a 9 win team with just a couple of breaks going their way.
