They've both played well, especially Williams, but I remain skeptical of their games. I honestly don't know exactly why. I just don't believe they are long-term rotation players on a championship team. I think they're both legitimate NBA players, but more like 9, 10 or 11 on the depth chart of a good team. I therefore wouldn't do anything for them that could affect my flexibility and ability to sign a legitimate rotation guy.
Only caveat to the above is if Shawne keeps shooting the way he's been, I reserve the right to reconsider, but I can't believe he will keep it up.
