If your hand's up, you're either a saint, ineligible to vote, or you're adopting the Mother Of All Budgets with the truth.
Mohammad Amir, one of cricket's finest emerging pace bowlers, made his mistake. He cheated with two older and more experienced cronies, and his moral code was corrupted on a global scale.

He was the man of that tainted series before evidence emerged of him no-balling by Monty Python Ministry of Silly Walks' proportions at Lord's -- he took six for 84 in the innings.
