charge question

[mutantducky]

Sorry I don't have the video. I was watching a bit of the Pacific v Alaska game(it was in Alaska and there was a bit of hometown cooking by the refs)

A Pacific player drove. Two Alaska players were there and the Pacific player went between them. The ref called a charge even though it looked like a block or a no call.
Just assuming the two defenders had LGP, and the offensive player goes for the space between them, about a foot or two. How much contact does there have to be to call a charge? So let's say the offensive player hits their arms that are sticking out a bit. Could that be a charge?
