Player Control or Block?

[JO]

Did the defensive player establish a legal guarding position?...from your post...I do NOT believe the defensive player did....Question: Is running parallel -- FACING the player with the ball?...I do NOT think it is ...FACING to me means that our chests are square to each other...NOT perfectly...we are NOT going to split hairs...but if my initial guarding position puts my chest pointed to the sideline and your chest is pointed to the endline...this is NOT establishing a legal guarding position...

What are your thoughts? ... JO
