To be clear, the offending dunker gets the technical. The head Coach gets an indirect technical, which removes their privilege to stand and coach their team.
So if B1 makes contact with the ball over the throw in line its a technical foul, if B1 makes contact with the thrower A1 by reaching over the line and slaps A1 hand it's an intentional foul? Just want to clarify if possible in my simple little mind. ;)
