I think When We are selecting the team we must select the 11 player according to their contribution in Fitness/last 5 Match performance in Batting , Bowling, fielding,
If some bady is not performing well h kept out from the team.. Chahe woh koi bhi ho , It must apply for all the player like sehwag/tendulkar/dravid/ganguly/irfan...etc.. Not perform kick him.. No Senior No junior team, Only Performer team...
