Sometimes when backing out or boxing out a player, the other player gives ground without really any contact. This is usually at the lower skill levels, but it still happens. If the contact causes them to move you have a foul, but if the player gives ground on his/her own do to incidental contact then you have nothing. The player should plant his/her feet and make the contact displace them. Then you have a foul!
