Thats what has happened with Jadeja, and I think he was lucky to escape with a ban of 5 years but of course his cricketing career is over. Because 5 years is big long period in this competitive world of cricket.
I agree that he was a good player and specially in one dayers, he was just the right kind of player to slog the bowlers in the end overs, and he was very successful in that role, he was a good all rounder with brilliant fielding abilities.
But I dont understand why did he cheat his country, his fans and all those cricket lovers who follow cricket as a religion.
