Just because A1 lands with both feet does not constitute this a legal jump stop.

If A1 ends his dribble with a foot on the floor, jumps off that foot with the intention to shoot but seeing B1 will block the shot decides to land with both feet simultaneously, are you saying you would call a travel?
