Trust is the big issue. How are we going to feel watching Smith or Warner walk out to bat next summer, hit a four, score a ton? One of the bowlers come on and produce a match-winning spell when it looks like not much is happening?
Should they be banned forever? No. Match-fixing is still the ultimate in that regard. ICC penalties are ordinary, but then we know what a disgrace that organisation is. 12 month bans would be about right IMO.
To me it sort of feels like the Rebel tours in the '80's - perhaps some older posters can comment a bit more on that. Our trust has been violated but in a couple years time we will be accepting these players for their talents as players, even if it is slightly guarded or not the way we once looked at them.
Regarding the restructuring of the leadership, I think there also needs to be a restructuring of the schedule. Warner and a couple of others in NZ right up till the start of the tour? Do the players get out amongst the schools and communities much anymore, either in Australia or South Africa? To me there should be some sort of requirement. I said to a non-cricketing mate about 20 years ago I felt cricketers cared more deeply about the game as a whole at all levels (this was around the time Taylor was captain and there was the suggestion of industrial action) whilst AFL footballers were more in it for themselves. After the last few years, especially with the advent of IPL and BigBash etc, I'm not sure that is the case anymore.
