It all depends on what direction the Lakers take this summer. If they trade Odom for basically two rookies and cap space, they could take a step back while the young guys work hard to learn the system.
Banks will help defensively and he will produce on the offensive end of the floor. Kwame Brown may have found his niche, playing center for the Lakers. I can see him averaging 14 ppg, 9-10 rbg, and a few block shots. If Brian Cook could be more consistent, he can contribute double digit scoring with his shooting ability.
Ask me again in August and I'll have an answer.
