Tennis Commentary on the BBC?

I was watching the tennis on TV the other day And John Lloyd and Andrew Castle were talking to Sue Barker before a match. Andrew Castle was babbling the most utter nonsense, he loves the sound of his own voice. John Lloyd was staring at him like he wanted to tell him to shut his stupid mouth, but too polite to say anything. Pat Cash is another one, he can play tennis but can't do commentary worth a toss. Why can't the BBC get people who know what they are talking about. They Charge plenty for the Licence Fee. I find it annoying That We, The Licence payers, pay wages to these twats for talking like school children.
