Its obvious that Ganguly came into team due to Pawar influence. You don't need inside story for this, simple logic would tell you that if that wasn't the case he would have been in Surat getting ready for match against Gujrath. He was sure he has done enough licking of Pawar.
Sad that Sachin wanted to be a part of this. Unfortunately, he is also looking at his own future. Broken elbow and wearing body can bear the heavy bat only for a little more time. Was possibly afraid of his own faith.
