No! I don't think so.
Why are people coming to watch table tennis
a fast game, where the players are smashing the balls at the other side of the table.
a game, where defenders bringing ball for ball from 5 meters behind the table. This is fantastic and brings people back to watch our sport.
I myself hope, that the ITTF will limit the thickness of the sponges, so that defenders have better possibilities to return.
