Its different because the guys are on the bench. Its not like the players on the court are acting out skits after making a shot. Players on the sideline can do whatever they want after their team scores a touchdown.
They are sometimes within a foot of the opposing player. They are sometimes on the court. At the RAC they will be on the court as there is little room between the bench and the court. If i am a player running back on D and they are on the court within arms length of where I am running I'd shove them.
