Tricky b/c situation

[Nevadaref]

I saw a game film the other day and a play caught my attention. Thought it might be worth sharing here.

1. Team B scores. A1 quickly takes the ball OOB and makes a throw-in pass to A2 who is standing in the backcourt at the FT line extended near the sideline. A2 catches the pass, but in attempting to turn upcourt and start a dribble bounces the ball off his knee. The ball goes forward in a path parallel with the near sideline, bouncing 3 or 4 times on the floor. The final bounce is just in the frontcourt. A2 chases after the ball and is the first player to reach it. When A2 first makes contact with the ball both of his feet are in the backcourt and he is reaching forward in to the frontcourt. His first touch consists of pushing the ball to the floor with one hand to continue his dribble.
Violation or not and why?




2. Same play, but in talking with a friend, it became clear that changing only one aspect of the situation was instructive. A2 does not catch the throw-in pass from A1. The ball touches his hands, but slips between them and hits him in the chest, then drops down and deflects off his knee. The rest of the play is exactly the same.
