STANFORD -- Stanford sisters Nnemkadi and Chiney Ogwumike are thrilled to take on one mighty, Mile High challenge: stopping 6-foot-8 Baylor star Brittney Griner and the unbeaten Lady Bears.It's a matchup they've both been eagerly waiting for as they lead the Cardinal (35-1) into their fifth straight Final Four this weekend in Denver riding a school-record 32-game winning streak. Nneka Ogwumike faced Griner in an AAU game back in high school, and that's when she insists she learned to shoot 3-pointers because scoring in the paint was a big problem. But the senior feels like everybody else in the country has already faced Griner, and now she's finally getting that chance in her NCAA tournament farewell.
