I gave up on commentators a long time ago - I don't enjoy listening to any of them. Many of them are just ignorant fools who can spout statistics but seemingly don't understand the game and are far too busy having conversations with the co-commentators than actually giving an account of the play.
As for the co-commentators -sometimes it's hard to believe they were players themselves, given the stuff they come out with.
They're a waste of money, imo - nobody needs them. You don't have them at a live game so why on the telly? They don't improve the experience as far as I'm concerned, and I'd rather they just named the player in possession and kept their opinions to themselves.
I'd watch with the sound off if it weren't for the loss of atmosphere.
