Personally, Pat Summerall and Al Michaels are my favorites and after them...well...let's just call the rest of them hack announcers.
I prefer to watch the game with the volume off because I've been around long enough to know how the game is progressing, and the CONSTANT talk annoys the hell out of me.
I tried watching the Mike & Mike program and its all the same. Chat, chat, and more chat. If I don't watch that show, I certainly don't enjoy them calling the game.
I fired them when I turned the volume off.
