Her dominance continued on November 29, 2006, when she made another career-high 28 points and 10 rebounds for her second career double-double, which was the second-highest game total for a freshman in Michigan State history.
During the summer of 2007, DeHaan played at the 2007 FIBA Under-19 World Championship in Bratislava, Slovakia, leading the successful Team USA, which won a gold medal.
