EVANSTON, Ill. — If coach Brian Gregory has any criticism of Josh Heath, it's that the sophomore point guard sometimes doesn't look to shoot enough. But with Georgia Tech on the verge of blowing a big lead Wednesday night, Heath stepped up to make two big baskets in the final 2:30 and the Yellow Jackets fought off a late Northwestern charge for a 66-58 victory in an ACC/Big Ten Challenge game. "On both of those plays, he made really good decisions," Gregory said.
