Closely Guarded Part II

[RookieDude]

Ok, at the risk of piling on from a previous thread, here is a closely guarded scenario that may or may not support or clear up some discussion from said thread.

A1 has picked up his dribble and is holding the ball at the top of the key. A1 is trying to stall because Team A is ahead by Xpts. with XX seconds left. Coach A has this funky stall play which requires players A2-A5 to be at the division line, behind A1.
B1 is "guarding" A1 behind him, between A1 and his teammates, trying to prevent A1 from making a pass. There is nobody between A1 and the basket...but Coach A does not want A1 to shoot, he would like him to pass to a teammate. A1 is having a heck of a time getting rid of the ball because of B1's "defense".

My question...is this considered closely guarded by B1 on A1 if in fact B1 is within 6 feet and is "guarding" for at least 5 seconds?
Notes:
A1 does not want to go towards the basket...he's trying to stall.
Is A1's path relevant at this time?
Does any part of this scenario clear up anything from the previous thread?

Just stirring the pot a little...but in this scenario, I got closely guarded. Do we all agree with that call?
