ATHENS, Ga. — Louisiana Tech was so dominant in the first 13 minutes againstGeorgia on Saturday that its biggest challenge became avoiding tentative play. It was a pleasant dilemma that Louisiana Tech overcame, though not without a late scare. Alex Hamilton scored 20 points and Louisiana Tech led by 26 points in the first half before holding off a late Georgia comeback for a 79-71 victory in the second round of the NIT. The Bulldogs from Louisiana Tech used pressure defense — full-court and half-court — to cause turnovers that helped create a flurry of transition baskets and 3-pointers.
