1. Why is the center calling this? He has an offensive player on the block in his primary surrounded by two defenders, and also has another offensive player in his primary that could take a quick pass and shot. The center should be ready to pick up the secondary defender around the RA should the dribbler had gotten around his primary defender.
2. The lead also had a whistle on this play, and should have been given first crack at this play. To be fair, in the heat of the moment, you sometimes don't hear that second whistle, though. Heck, it's not like the lead didn't have a good look at the play, either.
3. I honestly can't tell if it's a block or a charge. At first I thought the defender moved into the dribbler as the dribbler was trying to drive around him, thus a "block" call. But then I thought the defender beat the dribbler to the spot of contact, after having gained LGP, thus a "charge" call. I'm leaning "charge", but not 100%.
