I too have a hand check for the arm bar.

As for the block, it could be argued that the defender, even if he initially had LGP, lost it and no longer had the right to be moving at the time of contact.

If I were to take that side, here is the reasoning:

The defender did have LGP. If the defender has LGP, he isn't required to continue facing the dribbler but is allowed to turn. So, the direction he is facing isn't relevant if he had never lost LGP.

The only question would then be whether the dribbler got far enough by the defender at any point to negate LGP. If so that would require the defender to reestablish LGP in order utilize the benefits of LGP...moving at the time of contact.

I think many officials will have declared LGP lost on this play when the defender turns because the dribbler is going around him at that point. The defender turns to run faster in order to get back into the path.

All that said, I don't think he lost LGP...thus, no block.
