Debacle Reason 1 : The "5+1+5" strategy
No, that wasn't the reason. The choice of the bowlers could have been different (Balaji in for Zaheer; No, I wouldn't have played Yadav, because he is a batting all-rounder, someone in the class of Ganguly, bowling wise), but the very idea of playing 5 regular bowlers was long over-due and it needs to be persisted with. Even when Sachin is back, unless the team has enough confidence in eking out 10-15 overs at less than 5 an over between Sachin/ Sehwag/ Saurav consistently, the "5-bowlers" strategy needs to be given a decent run. Even with the super-sub rule, having 5 regular bowlers in the starting XI and a batting all-rounder as the super-sub makes a lot of sense.
