I believe Diablo is throwing out the possibility that the foul occured before the ball was handed by the player that caught the kick to his buddy on the reverse. If so, the BS is the end of the related run, which is the spot of the handing (B-21, it looks like). Applying the 3-and-1 principle, the penalty is enforced from the BS, 1/2 the distance to the goal. B, 1/10, B-10.5. Eh?
Big difference. Makes the point that we gotta know when the foul occured.
In addition to knowing when the foul occurred, i.e. status of the ball, we have to watch for a loss of player possession in all running plays. So, contrary to an earlier post in this thread, someone on the crew needs to monitor the ball carrier, even if it is only with one eye. And, if there is a change/loss of player possession, report that information to the R and calling official.
Here's a relevant tip for the deep officials on free kick, especially in a 5-man crew. Both officials (B & R?) should watch both deep receivers immediately after one catches/recovers the kick. If both the ball carrier and the other would-be receiver run towards each other, it is likely that there may be a change of possession - handoff or pass. We need to be aware of the legality of the change of possession. Hence, keep 4 eyes on the ball carrier. However, if both the ball carrier and his teammate run in the same direction, the "off" official can take his eyes off the ball carrier.
Nice one, Devil Boy.
