Had time today to get an official answer on the question posed last night on blocked shots resulting in a held ball.
The possession arrow is a key component on how to properly score the possession in game stats.
When an offensive player shoots the ball, that counts as a field goal attempt, if the shot is blocked, it counts as a blocked shot for the defensive player.
If the blocked shot results in a held ball, if the possession belongs to the defense, the defender who blocked the shot gets credit for a defensive rebound. If the possession belongs to the offense, the shooter gets an offensive rebound off their own blocked shot.
A separate situation … assuming the shot is blocked and the ball is picked up by another defensive player, that defensive player gets credit for the rebound off the blocked shot, if that player is then tied up, depending on the possession arrow, should the ball stay with team who just got the rebound, then it’s nothing more than a held ball. However, if the rebounding player is tied up and the possession goes back to the team who just shot the ball and had it blocked, then after crediting the player with a rebound, you must credit them with a turnover and the player who created the tie up is credited with a steal.
Hope that helps clarify proper scoring of a blocked shot that results in a held ball.
