So what? uh, jumpshooting big men usually need someone else to create their shots for them. It's part of the reason why KG needed that team around him, while the Spurs won a title with a bummy roster in 03.
Parker was better during the finals, Duncan was more important overall
The rules are not the cause, we stopped seeing great post players coming into the league LONG before the rule change, so what are you saying? The last great big man was drafted in 97, and the hand check rules were not implemented until the 04-05 season, so please tell me what happened between 1997 and 2005. If you want to link it to the zone, then tell me where the post players went between 97 and 02.
Big men not staying in college long term has had more of an affect on post players than the rules. It's really not hard to see that guys entering the draft early is really the main cause of this. It took a cot damn personal tutor for Bynum to learn to play with his back to the rim.
Are you living under a rock? Go watch some AAU ball, the tallest kids on the floor typically have no desire to play in the post and have no idea how to operate with their backs to the rim.
It's easier to teach someone how to knock down a 17 footer than it is to work with them on playing in the low post not facing the rim, very little development takes place with NBA players during a season.
