A pass is a pass, a shot is a shot...

[Back In The Saddle]

So if we're going to consider this play to be a try...

NFHS 4-41-3 "The try starts when the player begins the motion which habitually precedes the release of the ball."

and

NCAA 4-71.3 "The try shall start when the player begins the motion that habitually precedes the release of the ball on a try. The ball does not need to leave the player’s hand. The arm might be held so that the player cannot throw; however, he or she may be making an attempt."

So then I suppose the try begins when the player begins to his motion to gather the ball for the throw off of the glass? In which case any illegal contact against the "shooter" from that moment on is a shooting foul?
