BOULDER — Leah DuBois is a 10-year-old basketball fanatic from Centennial who brought a homemade sign to the CU Events Center on Friday night for a marquee women’s matchup against Stanford. DuBois didn’t root for the Buffs. She cheered on the other Colorado team. Her colorful hand-written letters on white poster board told the story: ‘Welcome home Jana, Fran and Ashten.’ “I am so in awe,” DuBois said.
