The reason I am supporting Sourav for captaincy is based upon the following points :-
1) He is India's greatest left handed batsman and captain of all times ( Can anybody defy me!)
2) Rahul is just a good player but his captainship prowess is pea-sized. His victories has captain has come against minnows, oppositions having the main player's missing and mostly series on the subcontinent itself. When his bowlers are battered all over the field, he stands in the same position, having an expression like he his having an stomach ache. He doesn't motivate anyone and is an ineffective leader.
3) Sourav has lead this same team in South Africa, on this same pitches to World Cup finals. He has won a series in Pakistan and levelled the Aussies on their home turf.
4) Those who are whining about Sourav being prone to short pitched stuff, I would say that if his records are taken into consideration, then the whole world cannot bowl bouncers
