Most sports viewers have a good knowledge of the particular activity they choose to watch, I fail to understand the over commentary of the ‘experts’ who in my view often spoil the enjoyment. Television is a visual aid, and is not enhanced by a constant accompanying babble of what is blindingly obvious. Sports worst affected are Rugby League, Rugby Union, Golf and Cricket. Please can commentary be available via the red button? This would make many viewers’ enjoyment so much better!
