When Tennessee Tech takes the floor at Colonial Life Arena Friday afternoon it will be attempting a near-Herculean task: The No. 16 seeded Golden Eagles will try to upset No. 1 seed South Carolina. It’s a feat that just one team has accomplished in the history of the women’s basketball NCAA Tournament. That honor goes to No. 16 Harvard, who beat No. 1 seed Stanford 71-67 in 1998.
