The change was made ONLY, to eliminate the penalty of administering free throw(s) when a teammate of the throw-in commits a common foul during the throw-in. The change made the penalty consistent with the penalty for other team control fouls. The penalty now is the awarding of a throw-in to the opposing team at the spot out-of-bounds nearest to where the foul occurred.

NOTE: Team control during a throw-in is not intended to be equated to player control status inbounds which creates team control status inbounds. During the throw-in, 10 seconds, 3-seconds, frontcourt status, backcourt status, closely guarded, etc... are not factors as there has yet to be player control/team control status obtained inbounds.

With this in mind, could we not say no team control and at least go to the arrow? B has made a good defensive play. It is unfair (sometimes NFHS rules are) to give the ball back to A.
