In many police cases, a culprit will become an informer to the police and give the names and clues to net in the bigger culprits in that case. Similarly, if this man is having any evidence he can come out openly and tell the concerned the names of players who are involved so that the big fishes also will come into the net like him. This is only a blame game. Azharuddin was also banned from cricket and he has become an MP. Like that Sreesanth can also try his luck in politics and become MP/MLA and then the scenario will get changed completely for him.
I think we have not heard the last of this saga, He can be the dark horse and file a RTI or approach SC or even write a book about fixing in circket. He has nothing to loose but BCCI can't afford to loose it's 'zero tolerance policy on corruption'.
