Will he score 20 or 3? Will he hit from deep or clang them? The Nets need to know what Yi Jianlian can do...every night. So far, the athletic, sweet shooting 7-footer is a mystery. There were games of 24 and 27 points, but also games of 0, 2, 3 and 4. Part of it is being young, part of it is confidence. Nets can't do anything about the former, but are trying to help the latter.
