Double Whistle

[Kansas Ref]

Using the "delayed-hitch" motion just before releasing the shot in the FT attempt is a time-worn stratagem used by players trying to "draw" a lane violation call. It's similar to in football, wherein either the QB will use long snap counts with lots of dramatic motions, head-bobbing, shoulder-faking, etc... to draw the 5 yards off sides penalty, or, when the offensive linemen use head bobs to pull the DT into the neutral zone.

So, regardless of the FT shooter's "intention" when using the hitch/delay motion in the act of FT shot attempt, if a lane violation occurred then we ought to decisively whistle it.
