I think alcohol bans are imposed by managers who are trying to get commitment from the lads. THe thinking is that if the lads have been off the stuff, they will see themselves as being very committed.
If such a player was asked what commitment was like, you can be sure that the firs thing he would say would be 'well, we're all off the drink anyway'.
