Last season Jason Kidd's veteranship/respect from teammates, oponents, and refferees were more valuable to the Knicks than Melo's high scoring .. Kidd's 19 yr career never needed a high-scorer or a first option scorer to make his team a winning postseason team. In the last 30 years Kidd / Bird /and Magic leads the NBA in the most Tripple-Double games, plus the trio leads the NBA in the most improve teammates performance.
In the past 12 yrs Jason Kidd has been one of the leagues TOP-3 team-complimentary (Gellin) players in the NBA.
What makes Jason Kidd such a high valuable player (that Cuban embarrasse himself last offseason) is Kidd always find a way to get all his teammates involve on offense/defense by making sure they score.
And that was hard task to do under HC Woody Plan "Give the ball to Melo or JR".
Carmelo Anthony career has been an individual high-scorer nothing else, which made Melo a Top-5 high-scorer in the past 6 seasons. Big-Big difference.
Melo was James Dolan idea of what the Knicks needed...
Marbury was Isiah idea of what the Knicks needed...
