When Windies had Roberts, Holding, Garner, Croft and Marshall (besides others) guess what they did. No, they didnt drop a middle order batsman to include all five fantastic fast bowlers, they dropped one of them. First one of the youngsters later Roberts, one of the greatest ever.
There have beeen many such instances in history. When India has Bedi, Prasanna, Chandra and Venkit, I think only once, if at all, they did anything as stupid as include all four great spinners and ask two of them to to open with the new ball. Although they were almost that bad when it came to who used the new ball.
Let Ganguly or Yuvraj decide they want to open from now onwards AND if the selectors and team management think that person (Ganguly or Yuvraj) will make a good opener, sure, include him.
Why do you want Rahul to open and for how long ? Till time is right to drop one of the middle order batsmen ?
Ridiculous.
BTW, if Gambhir doesnt deserve a place in the side, sure drop him but bring in someone who is an opener and an opener is not someone who opens in one test match every 20 tests he plays
