From ESPN.com's Graham Hays:
No. 16 Texas A&M beats No. 6 Duke. No. 9 Tennessee beats No. 4 Baylor. Georgia beats No. 8 Oklahoma. Oklahoma State beats No. 19 Georgia Tech. Upsets all (and that was just Sunday afternoon) by the definition of the word. But only upsets because it looks a little unseemly if there's a 300-way tie for No. 3 in the preseason polls.
One game doesn't prove anything, but Texas A&M's 95-77 victory is a reminder that we weren't working with proven facts to begin with and we need to at least be open to continually revising our hypotheses.
