posted by Laley23Right, and if I blow by the on ball defender, nobody else can slide in and take a charge. It’s bullshit basketball.
2 Things
1) LGP must be gained
2) Offense must initiate contact
In either situation, an offense can avoid it. There is also the concept of "space," and allowing an offensive player enough space to read, react, and make a move.
While these plays may suck to you as a fan, the defense is acting within the rules (assuming it is called correctly). If the offense is getting worse at reacting, you can't change the rule to penalize the defense (in my opinion). Again, all of this is under the blanket assumption that the rule/foul is being called correctly.
