Were you at the game or just reading about it? If you saw the game you would know that last nights rebounding had nothing to do with size. It was all hustle. Southern went for every loose ball including rebounds. Nebraska was very lackadaisical about rebounding and going after loose balls.
You never said they shouldn't move? You said we needed a player like UC Riverside's 7'1" player. He was big and slow. Seven footers who can run are few and far between and they aren't coming to Nebraska. They are going to traditional powers like Duke, UNC, Kentucky, etc.
