There is no legal block. There is no legal charge. They are merely fouls, and if they were legal, they wouldn't be fouls.

So, is a screen is illegal, by definition it is no longer a screen, but merely a foul.

But there is a difference.

The offending player in a block/charge is not trying to commit/set a block/charge. The block/charge is all by itself the failure to do something properly...thus it is illegal by definition.

However, a screen is a legal act and the player trying to commit/set a screen is doing so on purpose (usually) and is only charged with a foul when they do so improperly...when it is not a legal screen....or is an illegal screen.
