Why you want to bundle Ganguly with Sehwag? Ganguly is useless for ODI.He clings to another non performing players just to prove point for his place.
With VVS (VERY VERY SLOW) Ganguly in team if he clicks and consume one third balls of Indian Innings. That too in power play. We can Not score more than 240 runs.
Strike rate 73 multyply by 300 balls is 219 score. This means other have to score more than 100 strike rate to score more than 280 runs.
May be if other 200 balls available people have to score at strike rate of more than 105 just to reach 290 score.
So we can safely conclude If Ganguly scores we are likely to loose against Major team.
