Nneka and Chiney Ogwumike's memories of the one time they played basketball against each other at Stanford don't exactly match up.
They can agree on this: it was during practice when Chiney was a freshman and Nneka a junior.
"It was a little competitive," recalled Nneka. "She claims she didn't do anything, but she was fouling me. I told her she was going to regret it."
Chiney remembers catching an elbow and running off the court.
The end result was that the sisters never played against each other over the next two years when they were both at school.
"I think coach (Tara VanDerveer) figured out it wasn't going to be beneficial for us to be on opposing sides," Chiney said.
The two No. 1 picks in the WNBA draft will square off for the first time as pros when Nneka and the Los Angeles Sparks visit Chiney and the Connecticut Sun on Sunday. The Ogwumike parents and about 30 family members are coming to the game in Uncasville.
The sisters will meet in Los Angeles on Aug. 3.
