I believe if they have done anything wrong, ICC is there to penalise them and they have already done that. I give credit to Steve Smith for admitting to ball tampering. It is not first time that such a thing has happened in cricket. You will not see it more in T20 or a fifty-overs game because you have two new balls operating from both ends. These things come into play in the Test format where you have long sessions and players tend to do it more with the red ball. The kind of players Smith and Warner have been for Australia, it will be very sad that if any IPL side loses them. We should instead be looking forward. I don't think they deserve a harsh punishment especially when they have agreed to ball-tampering,
