"Variety of moves inside, really strong post passer and, wow, can this big girl handle the ball." -- Mechelle Voepel
Shawntinice Polk, Arizona, 6-5, sophomore
"Everyone's defense has been set up to stop her. No one has been successful yet." -- Nancy Lieberman

Stacy Stephens, Texas, 6-1, senior
"Texas is loaded with talent, but everything runs through Stephens." -- Nancy Lieberman
"Not tall, but strong and has great hands. And she just wears foes down inside." -- Mechelle Voepel

"Has been tremendous since her freshman season. Very good shot-blocker and post-up player." -- Nancy Lieberman
