Regardless of the sport, I am sure the reason we don't have the option to cut commentary audio but keep stadium/venue sound is because broadcasters know many viewers would press that button.
How I long to watch the snooker without being told x moves in advance 'he'll play the red along the cushion, screw back a foot or so to play the green then will put right hand side on the cue ball to head up to the red that's sitting just beside the blue spot, then he'll...'
SHUT THE FECK UP!!!
Appreciate that's a different thing to studio pundits but it's connected to the point.
