Good read and nice find but I have to disagree on a couple of things.
First off is the AP and Bell comparison.
Bell is younger and more athletic than AP and can keep up to the Kobes, etc wehn playing defense. AP has indeed lost a step in that regard but AP is a much better shooter and passer than Bell.
Jamario is much better on defense than Barnes but Barnes is a better shooter(slightly) for the author to say that either are good shooters is overstating their abitlities a bit.
