Mj was way better than magic and bird.
With the NBA rules of the 90's, LeBron would be the most dominating perimeter defender ever.
These are some of the rule changes that affected defensive play, and changed hand checking rules.
1994-95
• Hand-checking eliminated from the end line in the backcourt to the opposite foul line.
(also shortened the 3 point line to 22' from 23'9")
1997-98
• A defender will not be permitted to use his forearm to impede the progress of an offensive player who is facing the basket in the frontcourt.
1999-00
• In the backcourt, there is no contact with hands and forearms by defenders. In the frontcourt, there is no contact with hands and forearms by defenders except below the free throw line extended in which case the defender may only use his forearm. In the post, neither the offensive player nor the defender is allowed to dislodge or displace a player who has legally obtained a position. Defender may not use his forearm, shoulder, hip or hand to reroute or hold-up an offensive player going from point A to point B or one who is attempting to come around a legal screen set by another offensive player. Slowing or impeding the progress of the screener by grabbing, clutching, holding “chucking†or “wrapping up†is prohibited.
2000-01
• No contact with either hands or forearms by defenders except in the frontcourt below the free throw line extended in which case the defender may use his forearm only.
• Neither the offensive player nor the defender will be allowed to dislodge or displace a player who has legally obtained a position.
• Defender may not use his forearm, shoulder, hip or hand to reroute or hold-up an offensive player going from point A to Point B or one who is attempting to come around a legal screen set by another offensive player.
• Slowing or impeding the progress of the screener by grabbing, clutching, holding “chucking†or “wrapping up†is prohibited.
• A five-second count will begin if an offensive player with the ball and not facing-up starts dribbling below the free throw line extended while being closely guarded or starts dribbling outside and then penetrates below the free throw line extended while being closely guarded. (The five-second count commences when the offensive player penetrates the free throw line extended). After five seconds, a violation will have occurred and the offensive team will lose possession.
2001-02
• Illegal defense guidelines will be eliminated in their entirety.
• A new defensive three-second rule will prohibit a defensive player from remaining in the lane for more than three consecutive seconds without closely guarding an offensive player.
(3 second call replaced Illegal defense, which had multiple changes through out the 90s and early 2000s)
