I think the initial punishments for the trio were handled poorly. 12 months for Warner was fair. Bancroft as the junior player, led astray by Warner should have been 3-6 months. Smith, not directly involved but not strong enough a leader to have stopped it, basically removed from captaincy and maybe 3 months.
Anyway, that's all history now, I guess time will tell if Warner will be a more positive influence on the team this time around. Aussies tend to forgive the crimes of those that succeed for the country, Warner will get all the accolades that Smith has if he puts in a match-winning performance.
