Block/Charge

[johnSandlin]

What would you call here....B1 has established(and has been established for quite sometime, long enough to build a house with a garage attached) legal guarding position in the lane.

A1 drives to the bucket, and B1 square in the right side of the body. Whistle blows....Referee calls a block. B1 asks why, and referee says "because he hit in the leg."

I was not at this game, so I did not see this play. However, if this play happened as it was told to me, then in my judgement it is a PC/Charge foul, even though the contact was not in the torso area.

My two keys is "legal guarding position" and advantage/disadvantage. I have kind of went away from the right square in the torso line of thinking.

What would you call on this play?
