Simulated Fumble Foul

[tomes1978]

I'm a knew official and this is my first post, but here goes.

I say the ball becomes dead when it hits the ground. 7-5-5. B would take possession of the ball because the penalty is 5 yards and the loss of down. First and 10 for B at their 30.

EDIT:
OK maybe enforcement from the spot of the illegal pass (B's 21). So first and 10 B from thier 26.
