Again, I would be less inclined to care what mechanism one used to attempt the pass IF the board was running during the attempt. You know, receivers and defenders in motion during a pass (or run) play. WOW! What a revolutionary and novel idea for a game of football. Want to pass? Do it while the play is in actual progress. Want to pitch? Same applies.
Before this gets too far off topic, there are some (fairly) old provisions for "possession receptions" too. ::: Debate Question ::: "What if one wanted to simulate a possession reception or a pass where the receiver sits down in the soft spot of a zone?" Simple...... Put that receiver on a dead base. The board would still be running so all other players could (not have to) move while the attempt is made. None of this is new to the game. It's all been done before. Though the "possession reception" method was recently given a new name by Jimbo. "Matrix." I like it.
One more thing to add to your post MRD. Hand passes released behind the on-field QB and no higher than say a TTQB height above it. Many things have been used to see that passes are done consistently in a similar fashion. Some work better than others. Point is, I agree with most of what you said except for using the LOS as the release boundary. I think using the on-field QB's position is more appropriate. And that would include a mobile QB on the roll, run, what have you. I.E., follow him with your hand. It's all been done (successfully) before. So, nothing really new or innovative here.
I'm out of popcorn.
