I don't see Atewe as a starter in his freshman year. I also don't know why Petteway would start over Gallegos, Rivers, Fuller. He did not do much at Texas Tech.
Webster, Gallegos, Shields, and Pitchford seem like locks to start next year.
There will be a battle for that last forward spot between petteway, fuller, and rivers. I'm pretty high on Fuller, so I could see him starting next year. Biggs, Petteway, Hawkins, Rivers, Atewe, Vucetic, Parker is a solid bench though.
