Re: Please do this for the footy
It's been done and available for many years. Red button on the BBC offers it and certainly Sky used to have different audio options. BBC offer TV, Radio or "no commentary" options with the crowd noise and pitch mics still active.
As for the women's tennis I haven't watched a match in years. During the 90s when Sampras, Kraicjek and Ivanisevic ruined men's tennis as a spectacle women's tennis was fabulous. Since Seles, the Williams sisters, Kournikova et al started the grunting I just vote with the off switch.
Tennis is a professional sport which means it has to be entertaining enough for people to pay to watch it. If everyone refuses to watch grunters then the tournaments will have no option but to rule against grunting or risk losing sponsors.
