I'm going to side with Marbury on this one. I don't think he has changed his play much at all. Certainly he has a better attitude, but that comes from being in a better situation with better teammates. To me, his game is the same: he wasn't selfish before, and he isn't selfish now. He is an average defender -- not that there's anything wrong with that -- but certainly not among the NBA's "staunchest."
Similarly, Hardway's attitude is also better, but there's no way he's a more "complete basketball player" than when he was all-NBA in Orlando. I like Hardaway (usually), but the idea of him becoming a coach is laughable.
The author implies that Marion had a breakout season in rebounding last year. Of course that is not true. His rebounding numbers were even higher in '01-'02.
The Suns' center trio may be "reliable" in a narrow sense of the word, but they certainly aren't "productive," because they're rarely on the floor. Between the three of them, they averaged 28.8 minutes per game last season. That means that for nearly 20 minutes each game, the Suns had no center at all.
Joe Johnson became the sixth man as soon as he lost his starting job to Hardaway, which was very early in the season. Hardaway's injury put Johnson back in the starting lineup, but it's incorrect to say that Johnson became the sixth man at the end of the year. And there is absolutely no way Johnson could have been a sixth man award candidate, given the strength of the field.
Jacobsen's perimeter game was "remarkable" at Stanford. So far in the NBA, it is lousy, and that's a kind word for it. Based on last year, Jacobsen would be a solid bench contributor for no team in the league. The author is correct about Jacobsen's surprising ability to get to the basket, however.
It's gratifying to read an article which is positive, but I can't consider it particularly good with so many misconceptions.
