Video #1: First play is a charge. The player got LGP and got "set" right before the player went up.
The second play was clearly a charge for the same basic reason.
Video #2: It is really hard to tell where the contact came from. It might have been on the upward arm motion and then the player raised his hands where at that time there was no contact.
Video #3: That is not a double dribble. The ball was batted away and then controlled. A dribble has to be a controlled act. It is a judgment call, but IMO it was not a dribble on the first bat of this play.
Video #4: This should have been a foul. I guess the only issue is if he had contacted the ball to make it a shooting foul. And as a philosophy I would have considered this a shooting foul for the most part.
