DPI or Illegal use of the hands?

[Suudy]

This came up at our association meeting, so I want to get everyone's feedback.

Here's the situation somebody emailed me:

--------Situation--------------
A1 an end runs a route across the middle about 8 yards deep, defender B1 pushes A1 from behind while a pass from A2 is in the air. A2 is under pressure and as he is hit he throws the ball not in the direction of A1.

I know we do not have uncatchable pass but 7-5-11 (c) (new this year) says that it is not forward pass interference if: Contact by B is away from the direction of the pass. My take on it is we have DPI if the pass goes to the feet of A1 or over his head but not if it is thrown by A2 at an angle so that it leads him by 5 yards or trails him five yards.
-------End----------------------

My response to him was that I think if the ball is not obviously away from A2, it is DPI. Otherwise it is illegal use of the hands.
