Dude, he has been given too many chances no doubt but don't forget India is no Australia where if one player is dropped there are atleast 5 competent players fighting to occupy that place. There are not many players as aggressive, capable of destroying the opposition as Sehwag in the world. Bowlers feel the fear in the presence of Sehwag at the top of the batting order. He also gives the bowling option and if he clicks with the bat we know how effective he can be. The team management is taking a chance carrying him to carribean. Let's hope he clicks.
