was watching a girls Jr High game the other day. and noticed after the game the officiates chatting about number of players on the lane during a FT. If A1 is shooting a throw, the lane can be filled by a player on each side as follows, B, A, B on each side of the lane correct?

And not B, A, B, A on each side, correct?

I don't have my RB handy. Thanks!

You are correct
