Block/Charge

[DJ]

I was watching two other officials working a tournament last night and on two seperate occasions had B players who were standing in the lane get knocked down by Player A who came dribbling down the lane and while trying to get by them knocked the B player down. Player A got his head and shoulders past B as he tried to slip by but initiated the contact. The officials called a block in both cases. To me the only thing good about this call is that they were consistant. If player A tries to change direction that is not B's fault?
