The story is now part of Ogwumike lore. Nneka Ogwumike was out on the floor for the girls' first organized basketball practice clad in glasses and denim shorts.

Chiney, meanwhile, was in the bathroom crying and not coming out anytime soon after getting confused running the three-player weave drill.

But younger sister hides no longer.

Chiney Ogwumike has carved out her own place on the basketball court in every way -- as a player, as a personality, as a leader. She has never shied from comparisons to her older sister -- in fact, often she initiates them -- but the legacy Chiney has built at Stanford is all her own.

Heading into Big Monday's game against USC (ESPN2 and WatchESPN, 9 p.m. ET), Ogwumike is the Pac-12's all-time leading rebounder with nearly 20 games still left in her college career. She is in reach of becoming the conference's leading scorer, a record held by fellow Stanford star Candice Wiggins.

Ogwumike's final season has been her best yet, topping even last year's superb All-American effort. The 6-foot-4 senior forward is averaging 26.9 points per game, second in the nation behind Baylor's Odyssey Sims, and 12.2 rebounds per game for fourth-ranked Cardinal (18-1 overall, 7-0 Pac-12).

Ogwumike has scored at least 30 points in nine games this season, has been named the Pac-12 Player of the Week six times and has a strong case to be the national player of the year.

Still, she goes home after a game and stares at the stat sheet, looking for the places she has come up short.
