Fardin, its Will P's opinion, so I don't think you're in a position to tell him to make a 'smart choice'. You may not agree with his opinion but thats life!
The only time you saw him bat well was against the Australian's eh? Howabout the summer before that tour, against Sri Lanka and India, 2 scores in the 190's, that summer he totalled 2 50's and 4 100's. He made 156 against the South Africans the next summer. More recently, in the 2nd test against Sri Lanka he scored a 50 in the first innings, then a brilliant 100 in the second innings which saved the game. Indeed, in his last 12 innings Vaughan has scored 462 runs at 42.00, which may not be setting the world on fire, but isn't poor either I don't think. That run includes, 2 50's and 3 100's with a top score of 140.
Don't say that he only averages 42 in his last 12 innings because it was against poor opposition (being West Indies and New Zealand). I could say Langer only scored a double hundred against New Zealand today because he was playing against a poor team, and if I said that people would go on that i'm wrong. But that would just be my opinion
My Opinion is that hes not the best in the choice of players, but you wouldn't mind having someone who averages around the 45 mark in your side would you?
