The last non conference team that beat Duke @Duke was St. John's 83-82 in 2000, Mike Jarvis was the coach and Bootsey Thorton leading scorer. They had 150 straight wins, ranked or not ranked. In 19 years, they had 10 close calls, Kent St 79-72 2006, Georgetown 61-52 2006, Mich St. 81-74 2004, Ohio St. 73-68 2012, Davidson 79-67 2009, Mich St. 84-79 2010, Indiana 54-51 2006, Rhode Island 82-79 2008, Belmont 77-76 2011, and Vermont 91-90 2013. Before St. John's, it was a 1 pt loss to Michigan 63-62 in 1996, with Robert "Tractor" Trailor. So now 3 non conference losses in the last 23 years, I would say that puts SF Austin (7-1) in elite class with @Alabama(3-4) next. In Duke's last 305 non conference games, they are 297-8(SF Austin gave them loss #9) and 542-66 89% win percentage overall at home(loss #67) under Coach K. If SF Austin finishes 27-4 or 28-3 or better, would that make it a signature win.
