LGP only grants a player the right to move/jump at the time of contact and not be guilty of a foul.
Legal position and Legal Guarding Position are not synonymous. LGP is only relevant in the context of contact with the defender's body,(block/charge) not their arms. What you're describing is illegal use of hands, not blocking.
Yes, the player has LGP, but has committed an illegal use of hands foul....which is not dependant on LGP.
Again, you're mixing blocking and illegal use of hands. Is it a foul, yes, but not a block and not because of the lack of LGP.
Read the definition of what a player who has LGP can do (4-23-3)
After the initial legal guarding position is obtained:
a. ...may have one or both feet on the playing court or be airborne...inbounds
b. ....not required to continue facing...
c. ...may move laterally or obliquely...
d. ...may raise hands or jump....
e. ...may turn or duck...
Note that ALL of these are movement actions. Having LGP merely allows these actions...that is it.
If the player is stationary (not moving) then they are not doing
a (foot in the air moving to a new spot),
b (turning away),
c (shifting),
d (jumping), or
e (turn/duck). So, they are not doing anything that required LGP to be legal.
Correct...but a stationary player is not judged using LGP. LGP is only needed to make actions I listed above legal in the event of contact.
