Yes, especially for football games. How can anyone listen to Pat Summerall? He was a very good announcer at one time but has no business being on the air anymore. I love to listen to Vin Scully do baseball games so if I'm watching the Dodgers on TV, I'll put the radio on when he moves over to the radio side and then put the TV sound back on when he comes back on TV.
I also watch Sportscenter pretty often with the sound off so I don't have to listen to Stuart Scott and the other clowns at ESPN that think they're bigger than the show.
