A link to the BR article would have been nice.

Tatum still has a long way to go to be considered in the same breath as true great players of this generation. His defense is spotty apart from being able to take advantage of his long arms to tip passes because he doesn't move/re-position his feet well in man defense. He was routinely beaten off the dribble by the player he was guarding both during the regular season as well as the playoffs.
His rebounding and help defense (particularly from the back side) was nearly non-existent and exposed during the post season. There were multiple games, especially during the 76'rs series, where an opposing player went in for an uncontested layup or dunk after beating his man while Tatum stood by on the weak side and made no effort (and I mean zero) to make a play on the ball as if he didn't know what to do....or was afraid of contact.
My biggest complaint, however, which I voiced repeatedly in game threads throughout the year, was that Tatum continually drove to the basket and had layup attempt after layup attempt (including more than one instance in the same game) blocked from behind or the side because he was bringing the ball up from at or below his waist and did not go strong all the way to the hoop.
You would think that CBS (and his assistant coaches) would have "broken" Tatum of that bad habit but no, he kept doing it over and over apparently "expecting a different result", which if I recall correctly, a certain reputed "genius" referred to as the definition of insanity.
In any case, Tatum has a nice stroke and step back jumper but a considerable way to go before becoming a complete player on both sides of the court at least IMNSHO.
